Connections
A connected number represents one paired WhatsApp account in a workspace.
WhatsApp API pricing without hidden assumptions
Understand how ChatRail prices connected numbers, message credits and optional AI usage—and which external costs may still apply.
Choose a tier based on operational volume, not a vague feature bundle.Message credits
Credits measure messages processed under the allowance shown for the tier.
Optional AI
Model usage applies only when context-aware AI replies are enabled.
What you are paying for
A ChatRail subscription covers the workspace, connection operations, API access, delivery state, inbound webhooks and the allowance shown for your plan. Higher tiers add capacity and operational controls. The current checkout or order form is the source of truth for exact allowances.
How to estimate a month
Count outbound alerts, expected inbound replies and meaningful seasonal peaks. Add headroom for delivery events, retries and testing. Do not size a production workflow from its quietest week.
AI is not the default cost
Core messaging does not require a model. When AI replies are enabled, usage depends on the selected provider, context size and conversation length. Apply per-connection limits and a maximum number of automated turns to keep cost and risk bounded.
Costs outside ChatRail
Your own hosting, workflow platform, database, model provider and operational support may have separate costs. Linked-device sessions do not create Meta Cloud API conversation fees, but that does not make the transport risk-free or official.

One WhatsApp account paired with a ChatRail workspace.
Does every delivery event consume a message credit?
Refer to the current plan definition at checkout; it should explicitly state what is counted.
Can I use ChatRail without AI charges?
Yes. Leave AI replies disabled and use the API and webhooks as standard messaging infrastructure.
