Exchanges fail with the Exchange Rate error: the rate for this pair cannot be found, please try another pair
Troubleshooting exchange failures caused by missing currencies, pairs, or misconfigured rate providers in B2CORE
Problem
A client encounters the following error when attempting to exchange one currency for another in the B2CORE UI: Exchange Rate error: the rate for this pair cannot be found, please try another pair
.
Possible reasons
This issue may occurs due to one or more of the following:
One or both currencies aren't added in the B2CORE Back Office.
The selected currency pair isn't configured or is disabled in the B2CORE Back Office.
The exchange rate provider configuration is incomplete or incorrect.
Solution
To fix the exchange issue:
Verify that currencies exist in the B2CORE Back Office
Navigate to Currencies > Currencies.
Ensure that both currencies involved in the exchange are added. If not, add the missing currencies (for details, refer to How to add a currency).
Verify that the currency pair is configured in the B2CORE Back Office
Navigate to Currencies > Currency pairs.
Confirm that the required currency pair is configured and enabled. If not, add or enable it (for details, refer to How to add an exchange currency pair).
Check that the exchange rate provider is properly configured in the B2CORE Back Office
Navigate to Currencies > Rates.
Locate the provider used to supply rates for the required currency pair, for example B2BINPAY, and click the Edit button to open its details.
Verify its configuration and credentials (for details, refer to How to configure currency exchange rates).
After confirming that currencies, currency pairs, and provider settings are correctly configured, the exchange should work without errors.
