Workflow actions often call external providers. Those calls can take time or fail, so Payrails sends a notification to your server when each action finishes.

Configure your server for receiving notifications before you continue.

Every notification uses the same envelope:

event: Type of event that happened.
time: Date and time of the event.
details: Event-specific details.
workspaceId: Workspace identifier.
eventTrigger: Reason the event was triggered. One of api, action, or external.

Event types

The following events trigger notifications during a workflow.

Event type	Description	Example
`executionCreated`	A new execution started for a workflow, such as a payment for an order.	An execution for order `3573894940903` started.
`executionActionRequested`	A specific action, such as authorization, was requested for an execution.	A request authorized a payment for €12.50 with a credit card.
`ruleEngineExecuted`	The rule engine evaluated rules for a transaction to determine provider or payment priorities.	A rule evaluated the customer's country (`DE`) and operating system (`ios`) for provider selection.
`executionActionCompleted`	A specific action in the workflow completed successfully.	A card authorization processed successfully.
`executionActionUpdated`	A previously requested action changed status or result, such as an authorization moving from pending to success.	An authorization moved to a successful state.
`networkOffersEnrollmentCompleted`	A payment instrument enrolled successfully in a network offers program.	A Visa card enrolled in a rewards program during a transaction.

Structure of the `details` object

The details object has a small set of top-level envelope fields. Most payment-specific fields — operationType, operationResult, authorizationCode, acquirerReference, providerReference, paymentInstrument, threeDS, and others — sit inside each entry of the paymentComposition array.

📘
The actionId in each notification matches the one returned in the response to the action you performed on the execution.

Top-level `details` fields

Field	Type	Description	Example
`action`	Enum	Type of action that was completed.	One of: `authorize`, `confirm`, `capture`, `cancel`, `refund`.
`actionId`	UUID	Identifier of the action, also returned when the action started.	`"b0c28520-eca0-4be6-8771-99c43144bdaf"`

`success`	Boolean	Whether the full action succeeded.	`true`
`errors`	Array	Errors for the action. Populated when `success` is `false`. See errors.	`[]`
`execution`	Object	Summary of the execution. See execution details.	*
`amount`	Amount	Total amount of the execution. With multiple payments, this is the sum. Each `paymentComposition` entry carries its own per-payment `amount`.	`{ "currency": "EUR", "value": "10" }`
`paymentComposition`	Array	Payment attempts in the execution. Present on payment workflows. See paymentComposition details.	*
`payoutComposition`	Array	Payout attempts in the execution. Present on payout workflows in place of `paymentComposition`. Same structure as `paymentComposition`, with the equivalent payout-side fields.	*

`execution` details

Field	Type	Description	Example

Acquirer field availability

The acquirer fields acquirerReference, retrievalReference, acquirerMID, acquirerAccountCode, acquirerCountryCode, accountFundingTransaction, and authorizationCode are populated only when the provider returns them. Coverage varies by provider.

If a field your integration needs is missing and the provider does return it, contact your Payrails representative.

`email`	String	Cardholder email. Present only when supplied at instrument creation.
`billingAddress`	Object	Billing address. Present only when supplied at instrument creation.
`binLookup`	Object	Issuer information derived from the BIN.

The binLookup object contains:

`tokens` structure

Each entry in paymentInstrument.tokens[] describes a token associated with the instrument.

`type`	Enum	Token type. Common values: `psp` (provider-side token, such as Stripe `pm_*`), `vault` (Payrails vault token), `network` (network token).
`reference`	String	Token identifier in the corresponding system.
`meta`	Object	Provider-specific context stored with the token. For provider tokens, typically includes `holderReference` (the provider-side customer reference, such as Stripe `cus_*`).

Provider-specific details

To process a requested action, Payrails calls the external provider in its expected format and maps the response to a unified result.

Payrails extracts and maps the most important fields to unified fields and result codes. Two fields preserve the provider context:

operationProviderReference — identifier of the operation in the provider's system.
operationResultProviderDetails — provider fields used to derive operationResult. Populated on failures.

The following extract shows how Payrails reached the InsufficientBalance result based on three fields from Hyperpay's response. The message field contains the provider's human-readable description of the decline reason.

{
  "operationResult": "InsufficientBalance",
  "operationResultProviderDetails": {
    "message": "transaction declined (amount exceeds credit)",
    "additionalData": {
      "result.code": "800.100.155",
      "resultDetails.ExtendedDescription": "No sufficient funds",
      "resultDetails.response.acquirerMessage": ""
    }
  }
}

The keys in additionalData are JSON Paths to fields in the provider response. Hyperpay's response looked like this:

{
  "result": {
    "code": "800.100.155",
    "description": "transaction declined (amount exceeds credit)"
  },
  "resultDetails": {
    "ExtendedDescription": "No sufficient funds",
    "clearingInstituteName": "MADA via Postilion",
    "ConnectorTxID1": "90002550",
    "ConnectorTxID3": "|51|1008|929292||81374134||",
    "ConnectorTxID2": "299630|1231231232|123123123",
    "AcquirerResponse": "51"
  }
}

To include more provider-specific fields in your notifications, contact your Payrails representative to add them to providerResponseAdditionalFields inside each paymentComposition entry.

For the full raw request and response sent to a provider, use the Get Payment Operation Logs endpoint.

`errors` details

Notifications describe errors at two levels:

The top-level errors array describes the overall action result.
The errors array inside each paymentComposition entry describes the errors for that specific payment attempt. This separation matters most for workflows that generate multiple payments per execution.

For the structure of each error item, see error structure.
