# 1msg Ruby SDK Official Ruby SDK for the **1msg WhatsApp Business API**. This document is generated from the public OpenAPI contract. It covers install, auth, quick start, and every public operation available in the client. | | | |---|---| | **RubyGems** | [`one_msg_sdk`](https://rubygems.org/gems/one_msg_sdk) | | **Source** | [github.com/1msg/1msg-sdk/ruby](https://github.com/1msg/1msg-sdk/tree/main/ruby) | | **API docs** | [docs.1msg.io](https://docs.1msg.io/) | | **Platform** | [platform.1msg.io](https://platform.1msg.io/) | | **Support** | support@1msg.io | | **OpenAPI version** | 1.0.0 | | **Operations** | 60 | | **AI agent guide** | [AGENTS.md](./AGENTS.md) | --- ## Install ```bash gem install one_msg_sdk -v 2.0.1 ``` ## Requirements | Variable | Where to get it | Example | |----------|-----------------|---------| | `baseUrl` | Platform → channel → API host | `https://api.1msg.io` | | `instanceId` | Platform → channel id | `ODI371267300` | | `token` | Platform → channel → API token | JWT or API key | Use environment variables (`MSG_API_TOKEN`, `MSG_INSTANCE_ID`). Never commit tokens. ## Quick start ```ruby require 'one_msg_sdk' OneMsgSdk.configure do |config| config.host = "https://api.1msg.io/#{ENV.fetch('MSG_INSTANCE_ID')}" end messaging = OneMsgSdk::MessagingApi.new messaging.send_message( ENV.fetch('MSG_API_TOKEN'), 'Hello from 1MSG SDK', nil, '12020721369@c.us' ) ``` ## Authentication All requests use query-token auth: ```text https://{baseUrl}/{instanceId}/{path}?token={token} ``` Pass the channel token as the first argument to generated API methods. ## Recipient addressing - `chatId`: `12020721369@c.us` (1:1) or `...@g.us` (group) - `phone`: country code + number, no `+` - Exactly one of `chatId` | `phone` per request ## 24-hour messaging window Free-form `sendMessage` only works inside the 24h customer-care window. Outside that window use `sendTemplate`. ## Client map ```ruby MessagingApi # send/list messages, media, interactive ProfileApi # getMe GroupsApi # create/list/manage groups FlowsApi # WhatsApp Flows lifecycle TemplatesApi # listTemplates ChannelApi # channel helpers CallingApi # calling WebhooksApi # webhooks ``` ## Package notes Gem name is `one_msg_sdk`. Module is `OneMsgSdk`. ## API reference API groups: calling, catalog, channel, flows, groups, messaging, profile, templates, users, webhooks. ### calling #### `getCallingSettings` Get calling settings WhatsApp Calling API settings (beta). Requires Meta Calling enablement on the WABA. Not production-complete — paths and webhook field names may change. Trial/subscription-limited channels are blocked. ```yaml http: GET /callingSettings operationId: getCallingSettings clientGroup: calling responses: 200, 401, 500 ``` #### `initiateCall` Initiate WhatsApp call Outbound Calling API (beta). Requires Meta Calling enablement and product consent. Not production-complete — verify on stage before relying on this in production. Trial/subscription-limited channels are blocked. ```yaml http: POST /initiateCall operationId: initiateCall clientGroup: calling responses: 200, 401, 500 ``` #### `updateCallingSettings` Update calling settings Update WhatsApp Calling API settings (beta). Requires Meta Calling enablement. Trial/subscription-limited channels are blocked. ```yaml http: POST /callingSettings operationId: updateCallingSettings clientGroup: calling responses: 200, 401, 500 ``` ### catalog #### `createCommerce` Set Commerce Settings Update catalog/cart commerce settings via the `params` object. - `params.is_catalog_visible` — show catalog storefront icon (`true`) or hide it (`false`). - `params.is_cart_enabled` — enable cart (`true`) or disable it (`false`). Blocked when the channel subscription limit is exceeded. Requires a commerce-capable channel (Cloud Functions `/commerceWAV2`). ```yaml http: POST /commerce operationId: createCommerce clientGroup: catalog responses: 200, 401, 500 ``` #### `getCommerce` Get Commerce Settings Returns catalog/cart commerce settings for the channel. - `is_catalog_visible` — show catalog storefront icon (`true`) or hide it (`false`). - `is_cart_enabled` — enable cart (`true`) or disable it (`false`). ```yaml http: GET /commerce operationId: getCommerce clientGroup: catalog responses: 200, 401, 500 ``` ### channel #### `getConversationalAutomation` Get conversational automation settings Get WhatsApp conversational components for the channel (welcome message, ice-breaker prompts, and slash commands). Proxies Meta/360dialog `GET /conversational_automation`. When `enable_welcome_message` is true and a user opens chat for the first time, Meta delivers a webhook message with `type: request_welcome`. The inbound formatter exposes that as `type: "request_welcome"` and `meta.request_welcome: true` so your webhook can send a custom welcome reply. ```yaml http: GET /conversationalAutomation operationId: getConversationalAutomation clientGroup: channel responses: 200, 401, 500 ``` #### `getStatus` Get channel status Returns WhatsApp Business API client connection status. ```yaml http: GET /status operationId: getStatus clientGroup: channel responses: 200, 401, 500 ``` #### `setConversationalAutomation` Set conversational automation settings Update WhatsApp conversational components. Allowed body fields (others are ignored): - `enable_welcome_message` (boolean) - `prompts` (string[], max 4, each ≤ 80 chars) - `commands` (`{ command_name, command_description }[]`) Proxies Meta/360dialog `POST /conversational_automation`. ```yaml http: POST /conversationalAutomation operationId: setConversationalAutomation clientGroup: channel responses: 200, 401, 500 ``` ### flows #### `createFlows` Create Flow ```yaml http: POST /flows operationId: createFlows clientGroup: flows responses: 200 ``` #### `createFlowsFlowIdDeprecate` Deprecate Flow ```yaml http: POST /flows/{flowId}/deprecate operationId: createFlowsFlowIdDeprecate clientGroup: flows responses: 200 ``` #### `createFlowsFlowIdPublish` Publish Flow ```yaml http: POST /flows/{flowId}/publish operationId: createFlowsFlowIdPublish clientGroup: flows responses: 200 ``` #### `deleteFlowsFlowId` Delete Flow ```yaml http: DELETE /flows/{flowId} operationId: deleteFlowsFlowId clientGroup: flows responses: 200 ``` #### `getFlowsFlowId` Get Flow Details ```yaml http: GET /flows/{flowId} operationId: getFlowsFlowId clientGroup: flows responses: 200 ``` #### `getFlowsFlowIdPreview` Preview Flow ```yaml http: GET /flows/{flowId}/preview operationId: getFlowsFlowIdPreview clientGroup: flows responses: 200 ``` #### `getWhatsappBusinessEncryption` Get business encryption public key Retrieve the WhatsApp business public key and signature status for this channel's phone number. Required before publishing or sending Flows that use data encryption. ```yaml http: GET /whatsapp_business_encryption operationId: getWhatsappBusinessEncryption clientGroup: flows responses: 200, 401, 500 ``` #### `listFlows` List Flows ```yaml http: GET /flows operationId: listFlows clientGroup: flows responses: 200 ``` #### `patchFlowsFlowIdAssets` Update Flow Structure ```yaml http: PATCH /flows/{flowId}/assets operationId: patchFlowsFlowIdAssets clientGroup: flows responses: 200 ``` #### `patchFlowsFlowIdMetadata` Update Flow Metadata ```yaml http: PATCH /flows/{flowId}/metadata operationId: patchFlowsFlowIdMetadata clientGroup: flows responses: 200 ``` #### `setWhatsappBusinessEncryption` Set business encryption public key Upload and sign a 2048-bit RSA business public key (PEM) for this channel's phone number. Meta requires a signed key before Flow publish/send. Only one active key per number; a new upload replaces the previous key. ```yaml http: POST /whatsapp_business_encryption operationId: setWhatsappBusinessEncryption clientGroup: flows responses: 200, 400, 401, 500 ``` ### groups #### `createGroups` Create Group ```yaml http: POST /groups operationId: createGroups clientGroup: groups responses: 200 ``` #### `createGroupsGroupId` Update Group Info ```yaml http: POST /groups/{groupId} operationId: createGroupsGroupId clientGroup: groups responses: 200 ``` #### `createGroupsGroupIdInvitelink` Reset Invite Link ```yaml http: POST /groups/{groupId}/inviteLink operationId: createGroupsGroupIdInvitelink clientGroup: groups responses: 200 ``` #### `deleteGroupsGroupId` Delete Group ```yaml http: DELETE /groups/{groupId} operationId: deleteGroupsGroupId clientGroup: groups responses: 200 ``` #### `getGroupsGroupId` Get Group Info ```yaml http: GET /groups/{groupId} operationId: getGroupsGroupId clientGroup: groups responses: 200 ``` #### `getGroupsGroupIdInvitelink` Get Invite Link ```yaml http: GET /groups/{groupId}/inviteLink operationId: getGroupsGroupIdInvitelink clientGroup: groups responses: 200 ``` #### `listGroups` Get Groups List ```yaml http: GET /groups operationId: listGroups clientGroup: groups responses: 200 ``` ### messaging #### `createReadMessage` Mark message as read ```yaml http: POST /readMessage operationId: createReadMessage clientGroup: messaging responses: 200, 401 ``` #### `createUploadMedia` Upload media ```yaml http: POST /uploadMedia operationId: createUploadMedia clientGroup: messaging responses: 200 ``` #### `deleteMedia` Delete media from WABA storage Delete previously uploaded media by numeric `mediaId` (from `/uploadMedia`). This is the canonical deletion endpoint and uses the REST `DELETE` verb on the media resource path. The older `POST /deleteMedia` is a deprecated alias. ```yaml http: DELETE /media/{mediaId} operationId: deleteMedia clientGroup: messaging responses: 200, 400, 401, 500 ``` #### `deleteMediaLegacy` Delete media from WABA storage (deprecated alias) **Deprecated.** Use `DELETE /media/{mediaId}` instead. This POST alias is kept for backward compatibility with earlier integrations. New integrations should call `DELETE /media/{mediaId}`: 1msg follows REST conventions for resource deletion going forward (delete a resource with the `DELETE` verb on its resource path). ```yaml http: POST /deleteMedia operationId: deleteMediaLegacy clientGroup: messaging responses: 200, 400, 401, 500 ``` #### `getMmLiteStatus` Get MM Lite availability and status ```yaml http: GET /mmLiteStatus operationId: getMmLiteStatus clientGroup: messaging responses: 200, 401, 500 ``` #### `listMessages` Get messages list ```yaml http: GET /messages operationId: listMessages clientGroup: messaging responses: 200 ``` #### `retrieveMedia` Retrieve uploaded media metadata Get WABA media URL and metadata by mediaId (from uploadMedia). The returned `url` is temporary and typically expires within ~5 minutes. ```yaml http: GET /retrieveMedia operationId: retrieveMedia clientGroup: messaging responses: 200, 400, 401, 500 ``` #### `sendAddressMessage` Send address request message Request shipping address from the user (WhatsApp interactive `address_message`). **India and Singapore only.** Requires: - Business WhatsApp number registered in that country - Recipient phone matching the country (`+91` ↔ `IN`, `+65` ↔ `SG`) Pass `country: "IN"` or `country: "SG"`. Eligibility is validated upstream; mismatches (e.g. Singapore phone with `country: "IN"`) return errors such as `Unsupported Interactive Message type` (HTTP 200 with `sent: false`). Optional action parameters: `values`, `saved_addresses`, `validation_errors`. ```yaml http: POST /sendAddressMessage operationId: sendAddressMessage clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendButton` Send Reply Buttons Message ```yaml http: POST /sendButton operationId: sendButton clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendCarousel` Send Carousel You can send product cards via Carousel in two ways: Template messages: do not require a 24-hour customer service window between you and the recipient. Use sendTemplate. Free-form messages: can be sent only when a customer service window is open between you and the recipient. Use sendCarousel. The message structure in /sendCarousel is largely similar to sending a template. However, in this case you must explicitly specify all elements that are created in advance when working with templates. This is because the message is sent without using a template. In /sendCarousel, for sending a Catalog Carousel there can be either 1 URL button or one or more quick reply buttons. ```yaml http: POST /sendCarousel operationId: sendCarousel clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendContact` Send a Contact ```yaml http: POST /sendContact operationId: sendContact clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendCtaUrl` Send CTA URL interactive message Send an interactive message with a single call-to-action URL button. ```yaml http: POST /sendCtaUrl operationId: sendCtaUrl clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendFile` Send a File Send a file to an existing chat. (Only if the dialogue has an Open Session). Only one of two parameters is needed to determine the destination - chatId or phone. ```yaml http: POST /sendFile operationId: sendFile clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendFlow` Send WhatsApp Flow Message Send Interactive WhatsApp Flow message to an existing chat. (Only if the dialogue has an Open Session). Only one of two parameters is needed to determine the destination - chatId or phone. Use this method to send a published WhatsApp Flow as a service (interactive) message. If the 24-hour window is closed, send a template with a FLOW button via /sendTemplate. ```yaml http: POST /sendFlow operationId: sendFlow clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendList` Send List Message ```yaml http: POST /sendList operationId: sendList clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendLocation` Send a Location Send a location to an existing chat. (Only if the dialogue has an Open Session). Only one of two parameters is needed to determine the destination - chatId or phone. ```yaml http: POST /sendLocation operationId: sendLocation clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendLocationRequest` Send Location Request Message ```yaml http: POST /sendLocationRequest operationId: sendLocationRequest clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendMessage` Send a Message Send a message to an existing chat. (Only if the dialogue has an Open Session). The message will be added to the queue for sending and delivered even if the phone is disconnected from the Internet or authorization is not passed. Only one of two parameters is needed to determine the destination - chatId or phone. ```yaml http: POST /sendMessage operationId: sendMessage clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendOrderDetails` Send order details (India payments template) Send a WhatsApp **order details** payment / invoice message using a pre-approved **Utility** template that has an `ORDER_DETAILS` button. **India only** (WhatsApp Payments India). Requires: - India WhatsApp Business number - Commerce enabled on the channel (`GET`/`POST /commerce`) - Approved template with an `ORDER_DETAILS` button Use this method when you need structured fields (`order`, `referenceId`, `currency`, `paymentSettings`). The API appends a template button `sub_type: order_details` and sends via the same path as `POST /sendTemplate`. Works **outside the 24-hour session window** (template message). You can also send the same payload yourself with `POST /sendTemplate` by including a button component in `params`: ```json { "type": "button", "sub_type": "order_details", "index": 0, "parameters": [{ "type": "action", "action": { "order_details": { "reference_id": "order-123", "currency": "INR", "order": { "status": "pending", "items": [], "subtotal": { "offset": 100, "value": 50000 } } } } }] } ``` ```yaml http: POST /sendOrderDetails operationId: sendOrderDetails clientGroup: messaging responses: 200, 400, 401, 500 ``` #### `sendPaymentRequest` Send payment request (regional) Send a regional payment request interactive message (beta scaffold). `region` must be IN, SG, or BR. Payload shape follows Meta regional payments docs; verify on stage before production use. Full regional builders are not implemented yet. ```yaml http: POST /sendPaymentRequest operationId: sendPaymentRequest clientGroup: messaging responses: 200, 400, 401, 500 ``` #### `sendProduct` Send a Product ```yaml http: POST /sendProduct operationId: sendProduct clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendReaction` Send Reaction ```yaml http: POST /sendReaction operationId: sendReaction clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` #### `sendSticker` Send sticker message Send a WhatsApp sticker by mediaId or link URL. ```yaml http: POST /sendSticker operationId: sendSticker clientGroup: messaging responses: 200, 400, 401, 429, 500 ``` ### profile #### `getMe` Get Profile Info Get WhatsApp Business Account profile information ```yaml http: GET /me operationId: getMe clientGroup: profile responses: 200, 401, 500 ``` #### `updateMe` Update profile info Update WhatsApp Business Account profile fields. At least one of about, description, email, photo, address, vertical, websites is required. Blocked when the channel subscription limit is exceeded. ```yaml http: POST /me operationId: updateMe clientGroup: profile responses: 200, 401, 422, 500 ``` ### templates #### `addTemplate` Create message template ```yaml http: POST /addTemplate operationId: addTemplate clientGroup: templates responses: 200, 401, 500 ``` #### `listTemplates` Get templates list ```yaml http: GET /templates operationId: listTemplates clientGroup: templates responses: 200 ``` #### `removeTemplate` Remove message template ```yaml http: POST /removeTemplate operationId: removeTemplate clientGroup: templates responses: 200, 401, 500 ``` #### `sendTemplate` Send Template Message Send a WhatsApp template message (works outside the 24-hour session window). Supported `params` button `sub_type` values include: `url`, `quick_reply`, `copy_code` / `coupon_code`, `catalog`, `flow`, `limited_time_offer`, and **`order_details`** (WhatsApp Payments **India only** — requires an approved Utility template with an ORDER_DETAILS button). For India order/invoice payments outside 24h, include a button component: ```json { "type": "button", "sub_type": "order_details", "index": 0, "parameters": [{ "type": "action", "action": { "order_details": { "reference_id": "...", "currency": "INR", "order": {} } } }] } ``` Convenience wrapper with structured fields: `POST /sendOrderDetails`. ```yaml http: POST /sendTemplate operationId: sendTemplate clientGroup: templates responses: 200 ``` ### users #### `blockUser` Block WhatsApp user ```yaml http: POST /blockUser operationId: blockUser clientGroup: users responses: 200, 400, 401, 500 ``` #### `listBlockedUsers` List blocked WhatsApp users Returns users currently blocked on this WhatsApp channel (WABA `GET /block_users`). Same channel token auth as `blockUser` / `unblockUser`. ```yaml http: GET /blockedUsers operationId: listBlockedUsers clientGroup: users responses: 200, 401, 500 ``` #### `unblockUser` Unblock WhatsApp user ```yaml http: POST /unblockUser operationId: unblockUser clientGroup: users responses: 200, 400, 401, 500 ``` ### webhooks #### `getWebhook` Get webhook URL Returns the configured client webhook URL for this channel. ```yaml http: GET /webhook operationId: getWebhook clientGroup: webhooks responses: 200, 401, 500 ``` #### `setWebhook` Set webhook URL Configure the client webhook URL for inbound events. ```yaml http: POST /webhook operationId: setWebhook clientGroup: webhooks responses: 200, 401, 500 ``` ## Cookbook 1. Install the package from the registry above. 2. Set `MSG_API_TOKEN` and `MSG_INSTANCE_ID`. 3. Create the messaging client with `{baseUrl}/{instanceId}`. 4. Call `sendMessage` inside the 24h window, or `sendTemplate` outside it. 5. Use group/profile/flows/templates APIs for advanced workflows. ## FAQ **Where is the package?** See the registry link in the header table. **TypeScript has createClient — does this SDK?** Generated OpenAPI clients use per-API classes (`MessagingApi`, `ProfileApi`, …) instead of a facade. **Can I use this in a browser?** No — server-side only. Never expose tokens. ## Error handling | Code | Meaning | |------|---------| | 400 | Invalid parameters or body | | 401 | Invalid or missing token | | 429 | Rate limit exceeded | | 500 | Internal server error | ## Regeneration and versioning Docs regenerate with `node gen/generate-sdk-docs-langs.js`. Registry versions are immutable. ## License MIT © 1MSG
