# Refusal codes > Every code the seller door refuses with, its HTTP status and what it means. Source: https://connectors.integraledger.com/reference/refusals # Refusal codes A refusal is a JSON object `{"code", "sentence", "correlationId"}`. The `code` is one of the 47 below and is stable. The `sentence` is for people and may be reworded. The `correlationId` names the call in the door's log. Every `503` answer carries `Retry-After: 1`: retry the same request after a second. Every other refusal is final for the request as sent. The same codes are exported as `REFUSALS` from `@integraledger/agentic-connectors`, each with its status. ## 400 The body is not the operation's JSON object. | Code | Meaning | | ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | | `door/malformed` | The body is not the operation's JSON object: it is not JSON, it is not an object, or a member is missing, has the wrong type, or is not in the schema. | ## 401 No valid seller credential. | Code | Meaning | | ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | | `door/unauthenticated` | The request carries no seller credential, or one the door does not know. The answer carries `WWW-Authenticate: Bearer realm="seller-door"`. | ## 403 The request carries an Origin header; the door serves servers only. | Code | Meaning | | --------------------- | ------------------------------------------------------------------------------------------------ | | `door/browser-origin` | The request carries an `Origin` header. The door serves servers only; call it from your backend. | ## 404 Nothing known by that name for this tenant. | Code | Meaning | | ----------------------- | --------------------------------------------------------------------------------------------- | | `door/not-found` | Nothing is known by that name for this tenant: no such path, or no record with that ATR hash. | | `door/resource-unknown` | The `resource` names no resource declared for this tenant. | | `claim/unknown` | No record matches the hash the payment carries. | ## 405 | Code | Meaning | | ------------- | --------------------------------------------- | | `door/method` | The path is served, but not with this method. | ## 409 The record is in a state that does not allow this. | Code | Meaning | | --------------------------- | ------------------------------------------------------------------------------------------------------------------ | | `issue/mint-request-reused` | This `mintRequestId` was issued for different offers, content or request. A changed checkout needs a new id. | | `issue/mint-request-lapsed` | This `mintRequestId`'s record has lapsed. Append `:` with a new `n` and issue again. | | `claim/in-progress` | This ATR's payment is already claimed. On a retry of the same presentation, the first attempt won. | | `claim/paid` | This ATR is already paid. | | `claim/not-this-request` | The payment is not for the options and request this ATR was issued for. | | `claim/channel-open` | This channel is already open under an ATR. Serve its later requests yourself, and never claim them. | | `claim/channel-not-open` | No opening of this channel was claimed. Claim the opening first. | | `claim/agreement-first` | The record needs the agreement step, and the agreement payment is not recorded yet. Claim this payment once it is. | | `claim/instrument-claimed` | This payment instrument is already claimed for another record. | | `report/pairing-mismatch` | The report names a pairing other than the record's. | | `settle/other-reference` | This record was settled with another reference. | | `settle/not-settling` | The record is not in a state that allows this report. | ## 410 The challenge has lapsed. | Code | Meaning | | -------------- | -------------------------------------- | | `claim/lapsed` | The challenge for this ATR has lapsed. | ## 413 The body is larger than this operation accepts. | Code | Meaning | | ---------------- | ---------------------------------------------- | | `door/too-large` | The body is larger than the operation accepts. | ## 415 The body is not application/json. | Code | Meaning | | ----------------- | ------------------------------------------- | | `door/media-type` | The body is not sent as `application/json`. | ## 422 The request cannot be served as sent. | Code | Meaning | | -------------------------- | --------------------------------------------------------------------------------------------------------- | | `door/request-required` | The offer or claim is on an x402 surface and carries no `request` commitment. | | `door/chosen-required` | The report is for a record with no claim, and needs `chosen`: the option the payment paid, as issued. | | `door/reference-required` | The report needs a `reference` of 1 to 256 characters with no control characters. | | `door/receipt-required` | The paid report is for a confirm-only channel pairing, and needs the `receipt` its opening answered. | | `issue/input-bounds` | The request is outside the bounds the door accepts (for example more than 16 offers or 56 content slots). | | `issue/pairing-not-served` | An offer names a pairing the resource is not declared to serve. | | `issue/offer-refused` | An offer's pairing cannot place the hash in that option. The sentence names the pairing and its own code. | | `issue/mixed-protocols` | The offers name pairings of more than one protocol. One `issue` serves one protocol. | | `core/slot-name` | A content slot's name is not allowed: it must match `^[A-Za-z0-9][A-Za-z0-9._-]{0,63}$`. | | `core/slot-reserved` | A content slot uses a name the ATR reserves (`atrVersion`, `id`, or the binding's slot). | | `core/slot-duplicate` | Two content slots have the same name. | | `core/content-not-json` | A content slot's bytes are not exactly one JSON value (RFC 8259). | | `core/binding-not-json` | An offer cannot be recorded as JSON. | | `core/too-large` | The ATR would be larger than the size the door allows. | | `claim/pairing-unknown` | The pairing is not one this payment or the chosen option offers. | | `claim/not-bound` | The payment carries no ATR hash the door can read in the pairing's field. | | `claim/nothing-to-check` | The pairing carries nothing the buyer signs. Report the payment instead. | ## 503 Not available now; retry after one second. | Code | Meaning | | ------------------------------- | ------------------------------------------------------------------------------------------------ | | `issue/deadline` | The ATR was not ready in time. Retry with the same `mintRequestId`. | | `issue/contributor-unavailable` | A contributor the seller configured did not answer. Retry shortly. | | `issue/storage-unavailable` | The ATR could not be written to the seller's storage, so no challenge may go out. Retry shortly. | | `issue/store-unavailable` | The record store is not available. Retry shortly. | | `issue/capacity` | The record store is at capacity. Retry shortly. | | `claim/store-unavailable` | The record store is not available. Retry shortly. | | `claim/read-unavailable` | The landed payment could not be read on the rail yet. Retry shortly. | | `settle/store-unavailable` | The record store is not available. Retry shortly. |
