Channels at a glance
Before you send
- Numbers or agent credentials. Purchase a number or get an agent ID by registering an RCS campaign.
- Campaign approval. Ensure each number is attached to an active 10DLC/toll-free campaign, or your RCS agent is approved.
- API access. Create an API key on the Pinnacle Dashboard and store it securely.
Optional: Validate first
Use POST /messages/validate/sms,
POST /messages/validate/mms, and
POST /messages/validate/rcs to allow
you to validate content without sending. This will help you catch unsupported
files, return media size, display segmentation, and give cost estimates before
hitting send.
Send in three steps
Deliver
