First, sign up for an account. To get started with testing, create a free test agent via the Pinnacle Dashboard or the API (POST /rcs/test/agents). Your new agent will appear in the RCS Agents tab:
This gives you an RCS agent that you can test whitelisted devices on. Whitelist phone numbers and have recipients accept the tester invite before sending messages.
Each account can create up to 5 test agents. There is a 2-minute cooldown after creating an agent before you can whitelist numbers.
When you’re ready for production, you can register an RCS campaign with your company’s branding. While awaiting approval from carriers, you will be given a branded test agent that can send to whitelisted numbers. Once accepted by carriers, you’ll be able to send to any number, provided they have consented to receiving messages.
Navigate to Development > API Keys and click Create API Key. Give your key a descriptive name, then click Create. Once generated, copy your new API key and store it securely.
