Sandbox test credentials

Simulate different flows using Sandbox credentials

When using special Sandbox test credentials described on this page (other than user_good / pass_good), use the /sandbox/public_token/create flow or a non-OAuth test institution, such as First Platypus Bank (ins_109508). Special test credentials may be ignored when using the Sandbox Link OAuth flow.

Sandbox simple test credentials

Use the username user_good and password pass_good.

These provide basic account access.

Transactions testing credentials

Use the username user_transactions_dynamic and any password.

These credentials have realistic transaction history and update transactions and fire webhooks when /transactions/refresh is called. See transactions docs for details.

Auth micro-deposit testing credentials

Use the username user_good and the password microdeposits_good.

For more details, see Institution details for Auth testing.

Credit and Income testing credentials

Plaid provides a variety of pre-populated test users designed for use for Bank Income and other underwriting-related products.

Username	Password	Description
`user_bank_income`	`{}`	User with wide variety of income streams of different types
`user_credit_bonus`	Any	Has two salary streams: one with bonuses included in the paycheck, one with bonuses as separate transactions
`user_credit_joint_account`	Any	Has two salary streams and two identities on the account
`user_credit_profile_poor`	Any	Net loss cash flow over time, no consistent source of income
`user_credit_profile_good`	Any	Neutral cash flow over time, multiple gig economy income streams
`user_credit_profile_excellent`	Any	Positive cash flow over time, high salary-based income with secondary rental income stream
`user_prism_1` through `user_prism_10`	Any	For testing Partner Insights reports, these users return a variety of consistent partner insights values

Plaid also provides a GitHub repo designed specifically for testing credit products; look in the income directory for credit-specific users. You can modify these users as you need. For instructions, see Custom users.

For details on testing Bank Income with custom data, see Testing Bank Income.

Monitor and Identity Verification testing users

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.

Sandbox multi-factor credentials

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.

Bank of America and U.S. Bank cannot be used as test institutions when triggering MFA flows with modified passwords. Instead, these banks will always launch on Sandbox with an MFA flow.

ReCAPTCHA testing credentials

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.

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

Error testing credentials

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.

Error code password
1error_[ERROR_CODE]

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

Note that error testing credentials are not compatible with institutions that use OAuth. If you are not sure whether an institution uses OAuth flows, see the list of Sandbox institutions to find an institution that is guaranteed not to use OAuth.

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"USER_INPUT_TIMEOUT"
16"USER_SETUP_REQUIRED"

You can test several other OAuth-specific Link errors via the drop-down selector on the First Platypus OAuth screen after selecting any OAuth institution. The list of errors that can be simulated in this way is below:

 
1"INSUFFICIENT_CREDENTIALS"
2"ACCESS_NOT_GRANTED"
3"NO_AUTH_ACCOUNTS"
