Sertifier Rate Limits

Sertifier does not publish fixed numeric HTTP rate limits (requests per second or per minute) for the Credential API. The practical throughput ceiling for a program is the account's plan-based annual recipient allowance rather than a per-endpoint request cap - the API is designed to issue anywhere from tens to tens of thousands of credentials against that allowance. Sertifier's own guidance emphasizes reliability practices over rate limits: protect the secretKey, and guard the credential-issuance path with an idempotency check (for example enrolment ID + campaignId) so a completion event that fires twice does not double-issue.

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

It captures 3 rate-limit definitions, measuring requests, recipients, and credentials.

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

Tagged areas include Digital Credentials, Certificates, Credentialing, Rate Limiting, and Quotas.

Limits

Credential API Requests account
requests
not published
No fixed numeric request-rate limit is documented for the Credential API.
Annual Recipient Allowance account
recipients
per plan
The effective issuance ceiling is the plan's annual unique-recipient allowance (Free 250; paid tiers higher). Credentials per recipient are unlimited.
Bulk Credential Issuance campaign
credentials
designed for high volume (50 to 50,000+ per campaign)
Sertifier markets issuing tens of thousands of credentials via addCredentials; batch large jobs and verify server-side limits with support.

Policies

Idempotency
Guard the addCredentials call with an idempotency key such as (enrolment ID + campaignId), or use externalId / updateExistingCredentials, so a webhook or completion event that fires more than once does not issue a duplicate credential.
Secret Protection
Store the secretKey in a secrets vault, rotate it when staff change, and never embed it in client-side JavaScript.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on any 429 or 5xx responses during large bulk imports.
