About Esendex

Through Operate As, your agent, n8n workflow or code works in Esendex with your client's own access. Your client pastes their username from Esendex once. We store it encrypted, so it never sits in an email or a shared doc. Your agent reaches any endpoint of Esendex's API through the request tool, with the client's access attached.

Common uses in Phone and SMS
