MIT batches via SFTP
This feature allows merchants to send FlexCharge batches of failed transactions for subscriptions without integration.
Step 1. Create a Sandbox account
If you don't already have a Sandbox account with the required credentials to start using our APIs, you can request one at [email protected]
Step 2. Get credentials for our SFTP
Share with us your public SSH key so that we can provide a secured access to our server, as well as the IP address from which the batches will be sent, so that we can whitelist it.
We'll then create 2 dedicated folders for you: one for inbound files, one for outbound files.
Step 3. Authenticate
Use your AppKey and AppSecret to retrieve a bearer token and authenticate your requests.
How to /authenticate.
Step 4. Sandbox environment
Inbound
/transmit
Send a copy of every successful transaction as an array of /transmit. We will use it to build a customized risk model based on your volumes.
For Sandbox, send us a sample file containing some transactions. We will process it as a certification test.
For Production, you will send us the copies of your transactions through a daily batch. Please note that copies of transactions must be sent within 24 hours maximum.
| Format | JSON or .csv |
| Header | Must contain your - mid, your FlexCharge Merchant Identification Number. Get your Mid ID- Authorization: bearer, token retrieved by /oauth2/token |
| Body | An array of /transmit. |
| Maximum size per file | 2000 rows. |
| PCI data | No PCI data is required for this file, no need for tokenization. |
/tokenize
You will first need to /tokenize the payment method, and then send us a sample file containing failed transactions as an array of /evaluate. We will process it as a certification test.
No real PCI data in Sandbox environment
Make sure you only use whitelisted credit cards for the Sandbox.
/evaluate
We will process it as a certification test.

Possible status update for each transaction: APPROVED (the order was successfully rescued by FLexCharge) or EXPIRED(FlexCharge couldn't rescue this transaction during this period of time)
Step 5. Production environment
Once we have validated that the entire flow runs as expected, we will then move to production environment.

Send only MIT that have just failed
The FlexCharge service is optimized to work with failed Merchant Initiated Transactions (MIT) that have just failed. These need to be passed to FlexCharge on that day (and not after a few days or weeks) and should not be retried by the Merchant up to the set expiry date.

Secured Processing
We will securely process the transaction file, by validating its format, running security checks, and then decrypting it.

- 1pm and 6pm UTC
Result will be known on:
- the next day at 12pm UTC
