MessengerClient

Usage
Methods
Debug Tips
Test

Usage

Get the MessengerClient instance using the getClient function:

const { getClient } = require('bottender');

const client = getClient('messenger');

// `client` is a `MessengerClient` instance
await client.sendRawBody(body);

Or, get the MessengerClient instance from the context:

async function MyAction(context) {
  if (context.platform === 'messenger') {
    // `context.client` is a `MessengerClient` instance
    await context.client.sendRawBody(body);
  }
}

Error Handling

MessengerClient uses axios as HTTP client. We use axios-error package to wrap API error instances for better formatting error messages. Calling console.log with the error instance returns the formatted message. If you'd like to get the axios request, response, or config, you can still get them via those keys on the error instance.

client.sendRawBody(body).catch((error) => {
  console.log(error); // the formatted error message
  console.log(error.stack); // stack trace of the error
  console.log(error.config); // axios request config
  console.log(error.request); // axios HTTP request
  console.log(error.response); // axios HTTP response
});

Methods

All methods return a Promise.
