Automate your company’s refund processes with OP Corporate Refund API

Get your refunds right with no manual work - OP Developer


Get your refunds right with no manual work

As businesses strive for efficiency and automation, refunding incorrect and unknown payments remain a source of manual labor. OP Corporate Refund API brings an up-to-date solution to the problem.

OP Corporate Refund API allows our corporate customers to refund erroneous payments in an easy, simple and efficient way. Instead of slow, manual work and contacting the payers personally, companies are now able to automate the whole process.

The benefits are evident for all parties: the companies save time and other resources, and the original debtor gets their money back faster.

Just like our previous Corporate Banking APIs, the Corporate Refund API is built using well-known technologies such as JSON, REST and OAuth 2.0, making integration to your systems smooth. For more technical details, see the API documentation.

Return payments effortlessly

Large companies with high inbound payment volumes often receive erroneous payment transactions. Sometimes the amount is incorrect. Occasionally the payment was meant for someone else and the payer mistyped the account number. Incorrect or unrecognized payments can’t be balanced with receivables.

In Finland, the receiver can’t usually see the account number of the payer, which has made sorting and refunding them a time-consuming process with a lot of manual work. A company has had to contact the payer personally to request their account number. Usually, the only available contact information is a mail address, so the only option is to resort to paper mail. At worst, it takes up to several weeks for the refund to be credited.

With the new Corporate Refund API, we’re bringing the refund processes to this decade – no more manual investigation and snail mail to customers. From now on, everything is automatic: you can initiate a refund using only the data of the original transaction. We'll take care of the rest and return the amount back to the original payer.
