Authentication

All requests to the MoSend API authenticate with an API key sent in the Authorization header.

Authorization header

Include your API key as a Bearer token on every request:

Authorization: Bearer ms_live_abcdef1234567890...

API keys

Generate, rotate and revoke API keys from the dashboard. Each key is shown only once at creation, so store it in a secrets manager.

curl https://api.mosend.dev/v1/domains \
  -H "Authorization: Bearer ms_live_..."

Keep your API keys safe. Never publish an API key in repositories, logs or client-side code. If you suspect a key has been exposed, revoke it immediately from the dashboard.
