Authorizations

​
Authorization
string
header
required

The MX Platform API requires basic access authentication using your client_id and api_key. These credentials must be Base64 encoded and included in the Authorization header of each API request to ensure secure access.

Here's an example using curl to access v20250224. Replace https://int-api.mx.com/endpoint with the actual API endpoint you wish to access and your Base64 encoded client_id and api_key.

curl -L -X POST `https://int-api.mx.com/endpoint' \
-H 'Content-Type: application/json' \
-H 'Accept: application/json' \
-H 'Accept-Version: v20250224'
-H 'Authorization: Basic BASE_64_ENCODING_OF{client_id:api_key}'
