Callback Request using Callback Profiles
Before proceeding with the Callback Profiles option, you need to have a callback profile created. For more information on how to create callback profiles, see the Callback Profiles page.
The callback profile contains all the information needed for our system to send back information to your system. Example: Callback URL, HTTP method, headers, and so on.
Notes:
- The Callback profiles option also supports static authentication based on username and password, API KEY, or any other method that does not require dynamic fields.
- If your callback URL requires authentication, you need to add all the needed headers and related values to your callback profiles.
- Kaleyra.io will automatically retrieve this information when generating the HTTP call to your callback URL.
Base URL
<https://api.kaleyra.io/v1/><SID>
Prerequisite
- Complete the KYC to access all the features in Kaleyra.io.
- Create an API Key. To view the API Key and the SID, see View API Key and SID.
- Create Callback Profile for SMS Channel to see how to create a callback profile for SMS channel with dynamic variables.
Note:
To know all the callback profile IDs, go to Accounts Settings > Callback Profiles page. You can filter the callback profiles on the listing page with Callback Profile Name, HTTP Method, and Created Date range for accurate results.
