Sandbox test credentials

The easiest approach to create Items in the Sandbox is by using the username user_good. This gives you some limited control over Sandbox Item creation flow. It is not as flexible as the custom Sandbox, as Item details such as accounts and transactions are hardcoded.

1username: user_good
2password: pass_good
3pin: credential_good (when required)

You can trigger any multi-factor authentication (MFA) flow that Plaid supports when creating an Item by using username user_good and modifying the password.

1username: 'user_good'
2password: 'mfa_device'

4# Code for all devices: 1234
5code: 1234

1# n-rounds of m-questions per round, where 0 <= i, j < 9
2username: 'user_good'
3password: 'mfa_questions_<n>_<m>'
4
5# answer_<i>_<j>, for j-th question in i-th round.
6answer: 'answer_<i>_<j>'

1username: 'user_good'
2password: 'mfa_selections'

1# n-rounds of m-questions with o-answers per question
2# 0 < n, m < 10 and 2 <= o < 10
3username: 'user_good'
4password: 'mfa_selections_<n>_<m>_<o>'

6# answer_<n>_<m>_0, for m-th question in n-th round.

You may trigger a reCAPTCHA in Plaid Link in the Sandbox environment by customizing the test account password. Possible values are good or bad. A value of good will result in successful Item creation and bad will result in a RECAPTCHA_BAD error to simulate a failed reCAPTCHA. Both values require the reCAPTCHA to be manually solved within Plaid Link.

1username: user_good
2password: {"recaptcha":"bad"}

You can trigger several ITEM_ERROR or INSTITUTION_ERROR errors that you may encounter when creating an Item by using username user_good and modifying the password.

1error_[ERROR_CODE]

For example, the password error_ITEM_LOCKED allows you to simulate an ITEM_LOCKED error.

The list of errors that can be simulated in this way is below:

1"COUNTRY_NOT_SUPPORTED"
2"INSTITUTION_DOWN"
3"INSTITUTION_NOT_RESPONDING"
4"INSTITUTION_NO_LONGER_SUPPORTED"
5"INSUFFICIENT_CREDENTIALS"
6"INTERNAL_SERVER_ERROR"
7"INVALID_CREDENTIALS"
8"INVALID_MFA"
9"INVALID_SEND_METHOD"
10"ITEM_LOCKED"
11"ITEM_NOT_SUPPORTED"
12"MFA_NOT_SUPPORTED"
13"NO_ACCOUNTS"
14"PAYMENT_INVALID_RECIPIENT"
15"PRODUCTS_NOT_SUPPORTED"
16"USER_INPUT_TIMEOUT"
17"USER_SETUP_REQUIRED"

For automated micro-deposit testing, use the username user_good with the password microdeposits_good. For more details, see Institution details for Auth testing.

Monitor and Identity Verification have product-specific Sandbox users that can be used for testing. For more details, see Testing Monitor and Testing Identity Verification.

For Bank Income testing, use the username user_bank_income with the password {}. For more details, see Testing Bank Income.
