Sendpulse Rate Limits

The SendPulse REST API authenticates with short-lived OAuth2 Bearer tokens (valid roughly one hour) issued via POST /oauth/access_token. Beyond the token lifetime, the practical throughput constraints are the per-plan sending quotas (subscribers, emails per month, SMS credits, chatbot subscribers) rather than published per-second request limits. SendPulse may throttle abusive request volume; specific per-endpoint request-rate values are not published and are not reconciled in this artifact.

Sendpulse Rate Limits is the machine-readable rate-limit profile for SendPulse on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 5 rate-limit definitions, measuring seconds, emails, subscribers, messages, and requests.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Marketing, Email, SMS, Web Push, and Chatbots.

Policies

Token Refresh
Re-request an access token via POST /oauth/access_token when the current token expires (~1 hour).
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses.
Quota Scaling
Sending quotas raise as accounts move to higher plan tiers or purchase additional email/SMS credits.
