Response Payloads

When interacting with the Sequence Embedded Wallet API, each intent payload will trigger a corresponding response payload. This could be either a successful response or a prompt for a different action.

General Response Structure

Regardless of the specific response type, all responses have a standard structure with the following fields:

Name	Type	Description	Optional
code	string	Identifies the type of response	No
data	object	Holds content defined by response type	No

How to Detect

if (payloads.responses.isSentTransactionResponse(res)) {

  // It's a transaction receipt

}

Failed Transaction Response

The data field contains:

Field	Type	Description
error	string	The error message describing why the transaction failed.
request	SendTransactionPayload	The packet of transactions that were attempted.
simulations	SimulateResult[]	Results from the transaction simulation attempts.

SimulateResult:

Name	Type	Description	Optional
executed	boolean	Whether the simulation was executed	No
succeeded	boolean	Whether the simulation succeeded	No
result	string \| null	The result of the simulation	Yes
reason	string \| null	Reason for failure, if simulation failed	Yes

How to Detect

import { payloads } from '@0xsequence/waas';

const res = ... // response from the Embedded Wallet API

if (payloads.responses.isFailedTransactionResponse(res)) {

  // It's a failed transaction

}

Signed Message Response

Triggered after a successful sign message intent. The code is signedMessage.

The data field contains:

Name	Type	Description	Optional
message	string	The signed message	No
signature	string	The signature	No

Example

{

  "code": "signedMessage",

  "data": {

    "message": "Hello World",

    "signature": "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"

  }

}

How to Detect

import { payloads } from '@0xsequence/waas';

const res = ... // response from the Embedded Wallet API

if (payloads.responses.isSignedMessageResponse(res)) {

  // It's a signed message

}

Session Opened Response

Occurs after successfully executing an open session intent. The code is sessionOpened.

The data field contains:

Name	Type	Description	Optional
sessionId	string	Session ID (resembling an address)	No
wallet	string	The Sequence wallet address	No

Example

{

  "code": "sessionOpened",

  "data": {

    "sessionId": "0xBdeAfd3ee0550a73f615D2BaEA2E3D6d48FC857D",

    "wallet": "0x44c2Ea42Fb006a613a7b41D142576eD6B5055902"

  }

}

How to Detect

import { payloads } from '@0xsequence/waas';

const res = ... // response from the Embedded Wallet API

if (payloads.responses.isOpenSessionResponse(res)) {

  // It's a session opened

}

Validation Required Response

Some actions may necessitate additional validation. In such cases, the response code is validationRequired.

The data field contains:

Name	Type	Description	Optional
sessionId	string	Session ID (resembling an address)	No

How to Detect

import { payloads } from '@0xsequence/waas';

const res = ... // response from the Embedded Wallet API

if (payloads.responses.isValidationRequiredResponse(res)) {

  // Validation is required

}

Note

Both sendTransaction and signMessage intents could require validation. Always check for a validationRequired response before assuming you’ve received a transaction receipt or a signed message.

import { payloads } from '@0xsequence/waas';

const res = ... // response from the Embedded Wallet API

if (payloads.responses.isValidationRequiredResponse(res)) {

  // Handle validation

}

if (payloads.responses.isSendTransactionResponse(res)) {

  // It's a transaction receipt

}
