You can view detailed information about the ITNIO TECH API, which includes SMS and voice APIs for all ITNIO TECH products.
The ITNIO TECH API has been fully upgraded to the new version. This upgrade maintains the same interface content while making several optimizations in documentation support, usage guidance, and user experience. The interface architecture has also been optimized and integrated, resulting in a further improvement in the access experience.
To further improve service consistency, we will gradually discontinue the old version of the API. The specific plan is as follows:
The new version will be updated starting January 19, 2026. The old version is expected to be discontinued on April 20, 2026. We recommend that you switch to the new API as soon as possible to enjoy better documentation support and a better user experience. For assistance, please contact technical support. See the old version: ITNIO TECH API Old Version
After logging in or registering a ITNIO TECH account, you can view your API Key (API Key) and Application ID (App ID) on the console.
Application ID and API key are necessary to call the API to send messages.
It only takes a few minutes to configure your API and start sending messages.

To ensure the security of API requests, the ITNIO TECH API supports HTTP Basic Authentication.
Use your API Key as username and API Secret as password.After completing the ITNIO TECH account registration, the system will automatically generate relevant credentials for you.
While using the API, you may encounter HTTP status codes or API error codes.
For complete descriptions, see the corresponding error and response status code descriptions.
ITNIO TECH's messaging and voice group calling API itself does not have a fixed call limit.
However, due to the rules of ITNIO TECH and some external communication operators, actual requests may be rate limited.
Precautions for using WEB sending or voice group calling
When send volume or call volume exceeds expected thresholds:
We recommend that you pass "Create sending task" And split tasks/send them in batches, which can effectively avoid speed limit problems and improve the overall sending success rate.
