  • RetriesRetries up to 2×, 500ms backoff, 30s timeout.

6 body fields

Request parameters for retrieving incremental transaction updates from a processor token.

client_idstringoptional
Your Plaid API `client_id`. The `client_id` is required and may be provided either in the `PLAID-CLIENT-ID` header or as part of a request body.
processor_tokenstringrequired
The processor token obtained from the Plaid integration partner. Processor tokens are in the format: `processor-<environment>-<identifier>`
secretstringoptional
Your Plaid API `secret`. The `secret` is required and may be provided either in the `PLAID-SECRET` header or as part of a request body.
cursorstringoptional
The cursor value represents the last update requested. Providing it will cause the response to only return changes after this update. If omitted, the entire history of updates will be returned, starting with the first-added transactions on the Item. Note: The upper-bound length of this cursor is 256 characters of base64.
countintegeroptional
The number of transaction updates to fetch.
Default:100
optionsobjectoptional
An optional object to be used with the request. If specified, `options` must not be `null`.

2 status codes
200Returns the transaction update status, account, added transactions, modified transactions, removed transactions, the `next_cursor`, the `has_more` indicator, and a `request_id`.
transactions_update_statusstringrequired
A description of the update status for transaction pulls of an Item. This field contains the same information provided by transactions webhooks, and may be helpful for webhook troubleshooting or when recovering from missed webhooks. `TRANSACTIONS_UPDATE_STATUS_UNKNOWN`: Unable to fetch transactions update status for Item. `NOT_READY`: The Item is pending transaction pull. `INITIAL_UPDATE_COMPLETE`: Initial pull for the Item is complete, historical pull is pending. `HISTORICAL_UPDATE_COMPLETE`: Both initial and historical pull for Item are complete.
Allowed:TRANSACTIONS_UPDATE_STATUS_UNKNOWNNOT_READYINITIAL_UPDATE_COMPLETEHISTORICAL_UPDATE_COMPLETE
accountobjectrequired
A single account at a financial institution.
addedarray<Transaction>required
Transactions that have been added to the Item since `cursor` ordered by ascending last modified time.
modifiedarray<Transaction>required
Transactions that have been modified on the Item since `cursor` ordered by ascending last modified time.
removedarray<RemovedTransaction>required
Transactions that have been removed from the Item since `cursor` ordered by ascending last modified time.
next_cursorstringrequired
Cursor used for fetching any future updates after the latest update provided in this response. The cursor obtained after all pages have been pulled (indicated by `has_more` being `false`) will be valid for at least 1 year. This cursor should be persisted for later calls. If transactions are not yet available, this will be an empty string.
has_morebooleanrequired
Represents if more than requested count of transaction updates exist. If true, the additional updates can be fetched by making an additional request with `cursor` set to `next_cursor`. If `has_more` is true, it's important to pull all available pages, to make it less likely for underlying data changes to conflict with pagination.
request_idstringrequired
A unique identifier for the request, which can be used for troubleshooting. This identifier, like all Plaid identifiers, is case sensitive.
defaultError response
error_typestringrequired
A broad categorization of the error. Safe for programmatic use.
Allowed:INVALID_REQUESTINVALID_RESULTINVALID_INPUTINSTITUTION_ERRORRATE_LIMIT_EXCEEDEDAPI_ERRORITEM_ERRORASSET_REPORT_ERRORBASE_REPORT_ERRORRECAPTCHA_ERROROAUTH_ERRORPAYMENT_ERROR
error_codestringrequired
The particular error code. Safe for programmatic use.
error_code_reasonstringoptional
The specific reason for the error code. Currently, reasons are only supported for OAuth-based item errors; `null` will be returned otherwise. Safe for programmatic use. Possible values: `OAUTH_INVALID_TOKEN`: The user's OAuth connection to this institution has been invalidated. `OAUTH_CONSENT_EXPIRED`: The user's access consent for this OAuth connection to this institution has expired. `OAUTH_USER_REVOKED`: The user's OAuth connection to this institution is invalid because the user revoked their connection.
error_messagestringrequired
A developer-friendly representation of the error code. This may change over time and is not safe for programmatic use.
display_messagestringrequired
A user-friendly representation of the error code. `null` if the error is not related to user action. This may change over time and is not safe for programmatic use.
request_idstringoptional
A unique ID identifying the request, to be used for troubleshooting purposes. This field will be omitted in errors provided by webhooks.
causesarrayoptional
In this product, a request can pertain to more than one Item. If an error is returned for such a request, `causes` will return an array of errors containing a breakdown of these errors on the individual Item level, if any can be identified. `causes` will be provided for the `error_type` `ASSET_REPORT_ERROR` or `CHECK_REPORT_ERROR`. `causes` will also not be populated inside an error nested within a `warning` object.
statusintegeroptional
The HTTP status code associated with the error. This will only be returned in the response body when the error information is provided via a webhook.
documentation_urlstringoptional
The URL of a Plaid documentation page with more information about the error
suggested_actionstringoptional
Suggested steps for resolving the error
required_account_subtypesarray<string>optional
A list of the account subtypes that were requested via the `account_filters` parameter in `/link/token/create`. Currently only populated for `NO_ACCOUNTS` errors from Items with `investments_auth` as an enabled product.
provided_account_subtypesarray<string>optional
A list of the account subtypes that were extracted but did not match the requested subtypes via the `account_filters` parameter in `/link/token/create`. Currently only populated for `NO_ACCOUNTS` errors from Items with `investments_auth` as an enabled product.
