Testing

Simulate payments to test your integration before launching in production

Solidgate’s sandbox testing capabilities, which encompass successful transactions, failures, fraud detection, and error modeling, are valuable for identifying potential issues and ensuring system stability.

By testing various payment methods such as card payments, Google Pay, Apple Pay, and PayPal, you can ensure interoperability and security, and prepare your integration for real-world scenarios.

Card payments

To test your Solidgate integration, use your sandbox channel with specific keys:

Guide
Learn to authenticate API requests and fix validation errors effectively. Webhook keys , which start with the prefix wh_pk_/wh_sk_ , allow for receiving simulated webhook notifications.
Guide
Learn to authenticate API requests and fix validation errors effectively. API keys , starting with api_pk_/api_sk_ , are used to make API requests within our sandbox.

Test scenarios are available to simulate processing , success , and failure , which are crucial for assessing your system’s readiness and reliability across varied payment conditions. Use the following test credentials to test:

5251033622437578	charge	failed
	recurring	success
	auth	failed
	settle	success
	void	success
	refund	success
The user attempts a direct payment, skipping pre-approval or authorization, leading to an immediate fund transfer. Test steps include creating an order in `processing` status, trying a payment, and checking if the order moves to `declined` status with a `fail` transaction.

Auth

4553815318053315	charge	success
	recurring	success
	auth	failed
	settle	success
	void	success
	refund	success
This scenario tests placing a temporary hold on funds, ensuring they are available for final transaction confirmation. Steps include creating an order `processing`, attempting authorization, and verifying if it fails `auth_failed`.

Settle

Card number	Operation	Result
5361074849060618	charge	success
	recurring	success
	auth	success
	settle	failed
	void	failed
	refund	success
This scenario involves a merchant attempting to finalize a transaction by capturing previously authorized funds, transferring the amount from the customer's to the merchant's account. Steps include successful authorization `auth_ok`, settlement attempt, and verifying if the transaction settles or fails.

Void

Card number	Operation	Result
5361074849060618	charge	success
	recurring	success
	auth	success
	settle	failed
	void	failed
	refund	success
The user initiates an authorization to temporarily hold a specific amount on their card, ensuring funds are available but not immediately transferred. This allows for final confirmation before transaction completion. Testing involves creating an order in the `processing` status, attempting authorization, and checking if the order transitions to the `auth_failed` status, indicating a failed authorization attempt.

Recurring

Card number	Operation	Result
4123212486997559	charge	success
	recurring	failed
	auth	success
	settle	success
	void	success
	refund	success
Establishing a recurring payment involves setting up a schedule for automatically charging the card at specified intervals for ongoing services or subscriptions. Test steps include executing an initial auth payment and successfully obtaining a token upon authorization. This token is then used for a recurring payment operation, with the transaction initially in the `created` status. The process is verified by ensuring the recurring transaction transitions to the `fail` status, indicating the recurring setup's failure, while the order transitions to the `declined` status if successful.

Recurring auth

Card number	Operation	Result
4123212486997559	charge	success
	recurring	failed
	auth	success
	settle	success
	void	success
	refund	success
The user initiates a process for a recurring payment that starts with an authorization step. This ensures the merchant can verify the card and secure funds before setting up automatic charges at specified intervals for ongoing services or subscriptions. The testing process includes executing an initial payment through `auth`/`charge`, obtaining a token upon successful authorization, then using this token for a recurring payment with an additional authorization step, and finally verifying the outcome of the recurring-auth transaction.

Refund

Card number	Operation	Result
4476284533825961	charge	success
	recurring	success
	auth	success
	settle	success
	void	success
	refund	failed
This scenario tests the refund process, intended to reverse a previously successful charge and return funds to the customer. The procedure involves confirming a successful payment `settle_ok`, initiating a refund, and validating the outcome. Successful refunds should transition the status to `refunded`, while failures maintain the original `settle_ok` status.

For initial one-time payment, using any amount not detailed below will result in standard approval, ensuring all subsequent recurring payments on that token are automatically approved. However, to initiate specific recurring or recurring auth payment outcomes, the first transaction (auth/sale) must utilize predefined amount values:

3D Secure enhances online payment security by verifying cardholder identity, reducing fraud, and shifting liability from merchants to card issuers. no 3DS success
666 for Guide
Challenge flow in 3D Secure 2 requires cardholder interaction for authentication, triggered by high-risk scenarios or regulatory mandates. challenge success
555 for Guide
Frictionless flow in 3D Secure 2 authenticates transactions silently, requiring no input from the cardholder for low-risk payments. frictionless success

To perform testing, request access to the PayPal sandbox account from your account manager.

To test failed payments, set the API request with currency to USD and a specific amount to trigger errors.
