Questions before you request
Is this an official Apple iMessage API?
No. Apple does not offer a public iMessage API for business messaging, and SendiMessage is not affiliated with or endorsed by Apple Inc. SendiMessage operates managed messaging lines that deliver over iMessage where supported, with automatic SMS fallback where configured.
Can customers reply?
Yes. Incoming replies are received on your line and delivered to your endpoint as a signed receive webhook event.
What happens when iMessage is unavailable?
On a hybrid line with fallback configured, the message is sent over SMS instead — no duplicate send. Your webhook reflects the channel that was actually used.
Do I need to operate hardware or infrastructure?
No. SendiMessage operates the messaging lines, routing, and delivery infrastructure. Your application only needs to call one REST API and receive webhook events — there's nothing to host, provision, or maintain on your side.
Can this connect to my CRM, support platform, or AI workflow?
Yes. The REST API and signed webhooks work with anything that can call an API or receive one, so it fits into CRMs, support platforms, and AI/automation workflows. Dedicated integration guides for platforms such as Salesforce, HubSpot, and Shopify are on the Integrations page.
Can I activate a line myself?
No. Lines are reviewed and provisioned by the SendiMessage team so we can confirm your country, use case, and volume before you go live.
How is pricing calculated?
Dedicated production lines start at $129 per line per month, with volume pricing for multi-line setups. The Developer Pilot is one line at the same starting rate. Message usage, provider-related charges, and onboarding scope are confirmed for your configuration during review.
