iSendPro Telecom is a messaging platform for sending SMS campaigns and transactional SMS, along with related services such as voice messaging and RCS. It provides SaaS tools and developer-facing messaging APIs for integrating outbound messaging into applications.
iSendPro exposes a documented SMS REST API with public machine-readable OpenAPI/Swagger specs and account `keyid` query-parameter authentication; its other listed protocols (HTTPS, SMPP, Mail2SMS) are only documented behind login and could not be mapped as public integration surfaces from public docs.

Create an account from Inscription, then in your iSendPro account open the “Mon compte” → “Mon API” section to find your account API key keyid. The API docs also say you must configure IP control there by whitelisting the calling IPs or disabling IP control if needed.
