Request / Response Headers

Learn which headers are used in Mobile Text Alerts API calls and responses.

Request Headers

Request headers contain information about the client request. These are the header types used by the Mobile Text Alerts API.

Authorization

The Authorization header is used for authentication in HTTP requests. It contains a token or credentials used to prove the client's identity. The Mobile Text Alerts API uses bearer token authentication with an API key.

Header structure: "Authorization: Bearer {myAPIKey}"

Example request:

curl -L \
  -H 'Authorization: Bearer 89fa747a-e01b-5940-99c2-4e96fa996258' \
  'https://api.mobile-text-alerts.com/v3/auth/verify-api-key'

See Get an API Key to learn how to generate and send this key in a request.

Content-Type

Content-Type is an HTTP header that indicates the data type of the request's message body. This allows the server to understand how to process the request data.

All POST and PATCH requests to the Mobile Text Alerts API must include Content-Type: application/json

Header structure: "Content-Type: application/json"

Example request:

curl --location 'https://api.mobile-text-alerts.com/v3/groups/12345/subscribers/bulk-create' \
--header 'Content-Type: application/json' \
--data '{
    "subscriberIds": [
        123
    ]
}'
