The full reference, service by service
Every API documented with its endpoints, parameters, responses and ready-to-copy examples. Open the one for the service you are integrating — no sign-up needed.
Messaging channels
Certification & signing
Legally certified SMS notifications and contracts accepted from the phone, with their certificate.
Contracts for signature by SMS, email, RCS and WhatsApp, with authorization groups and multiple signature boxes.
Identity & security
Integration with your server
Receive every chat message on your server and reply with text, HTML and buttons.
Your server decides in real time what to do with each call: AI, menu, transfer or voicemail.
Each card shows the languages available for that specification (ES / EN). Questions while you integrate? +34 910 606 161 or mensatek@mensatek.com.
