Photon Health Rate Limits

Photon Health exposes a single GraphQL endpoint (POST https://api.photon.health/graphql) authenticated with an OAuth2 Bearer token. Photon does not publish specific public rate-limit values; quotas are managed per organization and OAuth2 client. Clients should expect HTTP 429 on throttling and implement backoff. Specific limit values are not reconciled in this artifact.

Photon Health Rate Limits is the machine-readable rate-limit profile for Photon Health on the APIs.io network, in the API Commons Rate Limits shape.

It captures 2 rate-limit definitions, measuring requests.

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Health, e-Prescribing, eRx, Prescriptions, and Pharmacy.

Backoff Strategy
Clients should implement exponential backoff with jitter on HTTP 429 and honor any Retry-After header.
Token Reuse
Cache and reuse OAuth2 access tokens until expiry rather than minting a new token per request.
