Sinch Node.js SDK for Conversation
The Sinch Conversation Node.js SDK allows you to quickly interact with the Conversation API from inside your Node.js applications. The fastest way to get started with the SDK is to check out our getting started guides. There you'll find all the instructions necessary to download, install, set up, and start using the SDK.
Syntax
When using the Node.js SDK, the code representing requests and queries sent to and responses received from the Conversation API are structured similarly to those that are sent and received using the Conversation API itself.
Note:
This guide describes the syntactical structure of the Node.js SDK for the Conversation API, including any differences that may exist between the API itself and the SDK. For a full reference on Conversation API calls and responses, see the Conversation REST API Reference.
mjs instead of a js file, and it uses Basic Authentication instead of OAuth2):// Find your App ID at dashboard.sinch.com/convapi/apps
// Find your Project ID at dashboard.sinch.com/settings/project-management
// Get your Access Key and Access Secret at dashboard.sinch.com/settings/access-keys

const ACCESS_KEY = '';
const ACCESS_SECRET = '';
const PROJECT_ID = '';
const CHANNEL = '';
const IDENTITY = '';

},

}
]
}

})
}
);

console.log(data);
}
run();This example highlights the following required to successfully make a Conversation API call using the Sinch Node.js SDK:
Client
When using the Sinch Node.js SDK, you initialize communication with the Sinch backend by initializing the Node.js SDK's main client class. This client allows you to access the functionality of the Sinch Node.js SDK.
Initialization
Before initializing a client using this SDK, you'll need three pieces of information:
- Your Project ID
- An access key ID
- An access key Secret
Note:
To start using the SDK, you need to initialize the main client class with your credentials from your Sinch dashboard.
const {SinchClient} = require('@sinch/sdk-core');
const sinchClient = new SinchClient({
projectId: "YOUR_project_id",
keyId: "YOUR_access_key",
keySecret: "YOUR_access_secret"
});Note:
For testing purposes on your local environment it's fine to use hardcoded values, but before deploying to production we strongly recommend using environment variables to store the credentials, as in the following example:
.env File
PROJECTID="YOUR_project_id"
ACCESSKEY="YOUR_access_key"
ACCESSSECRET="YOUR_access_secret" app.js File
const {SinchClient} = require('@sinch/sdk-core');
const sinchClient = new SinchClient({
projectId: process.env.PROJECTID,
keyId: process.env.ACCESSKEY,
keySecret: process.env.ACCESSSECRET
});Note:
If you are using the Node.js SDK for multiple products that use different sets of authentication credentials, you can include all of the relevant credentials in the same configuration object, as in the following example:
const {SinchClient} = require('@sinch/sdk-core');
const sinchClient = new SinchClient({
projectId: "YOUR_project_id",
keyId: "YOUR_access_key",
keySecret: "YOUR_access_secret",
applicationKey: "YOUR_application_key",
applicationSecret: "YOUR_application_secret"
});Conversation domain
The Sinch Node.js SDK organizes different functionalities in the Sinch product suite into domains. These domains are accessible through the client. For example,sinch.conversation.[endpoint_category].[method()].Endpoint categories
In the Sinch Node.js SDK, Conversation API endpoints are accessible through the client (either a general client or a Conversation-specific client). The naming convention of the endpoint's representation in the SDK matches the API:
messagesappcontacteventstranscodingcapabilitytemplatesV1templatesV2webhooksconversation
For example:
const response = await sinchClient.conversation.messages.send({
sendMessageRequestBody: {
app_id: "YOUR_app_ID",
recipient: {
identified_by: {
channel_identities: [
{
channel: "SMS",
identity: "RECIPIENT_number"
}
]
}
},
message: {
text_message: {
text: "This is a test message using the Sinch Node.js SDK"
}
},
channel_properties: {
SMS_SENDER: "YOUR_sms_sender"
}
}

Request and query parameters
Requests and queries made using the Node.js SDK are similar to those made using the Conversation API. Many of the fields are named and structured similarly. Additionally, path parameters, request body parameters, and query parameters that are used in the API are all passed as arguments to the corresponding Node.js method.
app_id: "{APP_ID}""app_id": "{APP_ID}"get method of the message class is invoked:const response = await sinchClient.conversation.messages.get({
message_id:"YOUR_message_id"
messages_source:"CONVERSATION_SOURCE"
});url = "https://us.conversation.api.sinch.com/v1/projects/" + project_id + "/messages/" + YOUR_message_id
payload = {
"messages_source": "CONVERSATION_SOURCE"
}message_id would be included as a path parameter, and messages_source would be included as a query parameter in the JSON payload. With the Node.js SDK, both parameters are included as arguments in the get method.Responses
Response fields match the API responses. They are delivered as JavaScript objects.
Pagination objects
For operations that return multiple pages of objects, such as list operations, the API response that would normally be an array is instead wrapped inside anApiPromiseList object. This object can take two forms, depending on how you have made the call:PageResult
If you are using a traditional await in front of the method, the ApiPromiseList will take the form of a PageResult, as demonstrated by the following example:const requestData: ListActiveNumbersRequestData = {
regionCode: 'US',
type: 'LOCAL',
pageSize: 2,
};
// This call will return the data of the current page wrapped in a PageResult
// We can then loop on the response while it has more pages
let response: PageResult<ActiveNumber> = await sinchClient.numbers.activeNumber.list(requestData);
// The ActiveNumber are in the `data` property
let activeNumbers: ActiveNumber[] = response.data;
console.log(activeNumbers); // prints the content of a pageconst requestData: ListMessagesRequestData = {
app_id: "YOUR_Conversation_app_ID,
channel: 'MESSENGER',
};
// This call will return the data of the current page wrapped in a PageResult
// We can then loop on the response while it has more pages
let response: PageResult<ConversationMessage> = await sinchClient.conversation.messages.list(requestData);
// The ConversationMessage are in the `data` property
let messages: ConversationMessage[] = response.data;
console.log(messages); // prints the content of a pagedata field and the object contains a hasNextPage boolean as well as a nextPage() function which can be used to iterate through the results.// Loop on all the pages to get all the active numbers
let reachedEndOfPages = false;
while (!reachedEndOfPages) {
if (response.hasNextPage) {
response = await response.nextPage();
activeNumbers = response.data;
console.log(activeNumbers); // prints the content of a page
} else {
reachedEndOfPages = true;
}
}// Loop on all the pages to get all the messages
let reachedEndOfPages = false;
while (!reachedEndOfPages) {
if (response.hasNextPage) {
response = await response.nextPage();
messages = response.data;
console.log(messages); // prints the content of a page
} else {
reachedEndOfPages = true;
}
}while loop.AsyncIteratorIterable
If you using an iterator (for await (... of ...)), the ApiPromiseList will take the form of a AsyncIteratorIterable object which can be used to iterate through the results, as demonstrated by the following example:const requestData: ListActiveNumbersRequestData = {
regionCode: 'US',
type: 'LOCAL',
pageSize: 2,
};
for await (const activeNumber of sinchClient.numbers.activeNumber.list(requestData)) {
console.log(activeNumber); // prints a single ActiveNumber
}const requestData: ListMessagesRequestData = {
app_id: "YOUR_Conversation_app_ID,
channel: 'MESSENGER',
};
for await (const message of sinchClient.conversation.messages.list(requestData)) {
console.log(message); // prints a single ConversationMessage
}With the iterator, the code is more concise but you have less control over the number of calls made to the API; the iterator will continue to make calls to the API to fetch the next page until the final page is returned.
