Cresora Commerce Documentation

Merchant lifecycle — create, submit for underwriting review, update, and close merchant accounts. Merchants progress through a state machine owned by Cresora Operations.

ℹServer-to-server API

Run the examples on this page from your backend against the sandbox host. The API sends no CORS headers, so browser JavaScript cannot read its responses, and an API key must never be exposed in a browser. There is no interactive console here. Generating a client instead? Download the OpenAPI spec (YAML).

GET/merchants

Authorization

BearerAuth

AuthorizationBearer <token>

Cresora API key, sent as an opaque bearer token in the Authorization header. Format:

csk_<prefix>_<random>

<prefix> — 8 URL-safe chars, shown in UI and logs for identification without revealing the full key (e.g. csk_Ab3kX9mQ…). Use ApiKey.prefix to match.
<random> — 24+ cryptographically random URL-safe chars.

Obtain via Partner Portal → Settings → API keys. Keys are only shown in full at creation/rotation time — Cresora does not retain the full value in retrievable form. Rotate any key that may have been exposed via logs, client code, or source control.

Query Parameters

cursor?string

Opaque pagination cursor from previous response. Do not parse.

Lengthlength <= 256

page_size?integer

Items per page (1–100).

Range1 <= value <= 100

Default25

state?string

Merchant lifecycle state.

Renamed 2026-08 (one-way): UNDERWRITING was UNDER_REVIEW and CONFIG_FAILED was BOOTSTRAP_FAILED. The retired values are never reused; REVIEWING keeps its wire value (displayed "Under Review"). Added 2026-08: ACTIVE (the gateway-provisioned resting state — the provisioning flow previously went straight to LIVE).

DRAFT — being edited by partner, not yet submitted
SUBMITTED — awaiting Cresora Operations review
REVIEWING — under active Cresora review (pre-underwriting; displayed "Under Review")
AWAITING_MERCHANT_SIGNATURE — Cresora pre-check approved; the merchant processing agreement is out for the authorized signer's signature. Signature completion moves it to UNDERWRITING; a declined or abandoned envelope moves it to REJECTED (REJ_008)
UNDERWRITING — submitted to Paysafe underwriting; status-only — the underwriting result transitions it to APPROVED or REJECTED
APPROVED — underwriting passed, awaiting provisioning
CONFIGURING — approved; per-processor payment-gateway provisioning in progress
CONFIG_FAILED — gateway provisioning failed after retries; an admin can retry (resumes at the failed step)
ACTIVE — gateway-provisioned and resting pre-go-live; probe/test transactions run in this window. Cresora Operations fires go-live once the go-live gate passes
LIVE — processing real payments
REJECTED — rejected with rejection_reason_code + rejection_reason (see RejectionCode)
AWAITING_CLARIFICATION — Cresora requested more information; editable by the partner, re-enters review on response
SUSPENDED — temporarily blocked by Cresora
CLOSED — terminal state, cannot transition out

Authorization

BearerAuth

AuthorizationBearer <token>

Cresora API key, sent as an opaque bearer token in the Authorization header. Format:

csk_<prefix>_<random>

<prefix> — 8 URL-safe chars, shown in UI and logs for identification without revealing the full key (e.g. csk_Ab3kX9mQ…). Use ApiKey.prefix to match.
<random> — 24+ cryptographically random URL-safe chars.

In: header

Header Parameters

Idempotency-Key*string

Client-generated unique key — a UUIDv4 is the recommended form. Cresora deduplicates within a 24-hour window scoped to the partner.

Format: 1–128 characters of letters, digits, . _ : -. Anything else is rejected with 400 validation_error. The character set is narrower than base64: padded base64 (+ / =) is NOT accepted, base64url is. The key is forwarded verbatim to the payment gateway on transaction creates, so it must satisfy the gateway's key contract too — rejecting locally gives you an actionable error instead of an opaque upstream failure mid-request.

Reserved prefixes — rejected with 400 idempotency_key_reserved:

hpp:, recurring: — Cresora's own server-minted deterministic keys. A client key in these namespaces could collide with a platform-generated record.
rb:, inv-charge:, inv-installment: — reserved by the payment gateway for its internally-minted keys.

Replay semantics:

Same key + same request body → Cresora returns the cached response from the original call. Response includes header X-Idempotent-Replay: true so the client can distinguish replays from fresh executions. Status code, body and side effects are identical to the original call.
Same key + different body → 422 idempotency_key_reused. Generate a new key and retry, or re-send the original body.
Key older than 24 hours → treated as a fresh key; no replay guarantee from beyond the window.

Retrying after an indeterminate failure. On 502 gateway_outcome_unknown the transaction is recorded as pending and the outcome is not yet known — retry with the SAME key (a fresh key risks a double charge) or poll the transaction. This is also what a gateway-side "an earlier request with this key is still in flight" response surfaces as.

Do NOT reuse keys across different partners. Scope is enforced per partner_id so the same key in partner A and partner B is independent.

Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

Create a merchant under the authenticated partner.

Whether a merchant transacts with real funds is governed by the gateway-side test flag on its reseller/merchant registration — the platform itself carries no per-merchant environment field. Onboarding a merchant for real processing requires partner certification to be CERTIFIED (see Capabilities.certification_status).

business_name*string

Legal business name. Bounded at 5–100 characters by the payment gateway's own validation — a shorter or longer value is stored but can never be provisioned for processing, so it is rejected here rather than at go-live.

Length5 <= length <= 100

contact_email*string

authorized_signer_name?string

merchant_category_code*string

ISO 18245 merchant category code (4 digits). Must be within the partner's certified scope; scope enforcement is a review-time control today (no mcc_outside_scope rejection is issued by this endpoint).

Header Parameters

Idempotency-Key*string

Client-generated unique key — a UUIDv4 is the recommended form. Cresora deduplicates within a 24-hour window scoped to the partner.

Reserved prefixes — rejected with 400 idempotency_key_reserved:

hpp:, recurring: — Cresora's own server-minted deterministic keys. A client key in these namespaces could collide with a platform-generated record.
rb:, inv-charge:, inv-installment: — reserved by the payment gateway for its internally-minted keys.

Replay semantics:

Same key + same request body → Cresora returns the cached response from the original call. Response includes header X-Idempotent-Replay: true so the client can distinguish replays from fresh executions. Status code, body and side effects are identical to the original call.
Same key + different body → 422 idempotency_key_reused. Generate a new key and retry, or re-send the original body.
Key older than 24 hours → treated as a fresh key; no replay guarantee from beyond the window.

Do NOT reuse keys across different partners. Scope is enforced per partner_id so the same key in partner A and partner B is independent.

Path Parameters

Header Parameters

Idempotency-Key*string

Client-generated unique key — a UUIDv4 is the recommended form. Cresora deduplicates within a 24-hour window scoped to the partner.

Reserved prefixes — rejected with 400 idempotency_key_reserved:

hpp:, recurring: — Cresora's own server-minted deterministic keys. A client key in these namespaces could collide with a platform-generated record.
rb:, inv-charge:, inv-installment: — reserved by the payment gateway for its internally-minted keys.

Replay semantics:

Same key + same request body → Cresora returns the cached response from the original call. Response includes header X-Idempotent-Replay: true so the client can distinguish replays from fresh executions. Status code, body and side effects are identical to the original call.
Same key + different body → 422 idempotency_key_reused. Generate a new key and retry, or re-send the original body.
Key older than 24 hours → treated as a fresh key; no replay guarantee from beyond the window.

Do NOT reuse keys across different partners. Scope is enforced per partner_id so the same key in partner A and partner B is independent.
