"Transaction not found" when Capturing payment transaction with Bambora

Question

I'm implementing the Inline Checkout from Bambora. The authorization step works without any problem. But when it comes to capturing the payment I always get the error Transaction not found.

This is what I do:

const options = {
    headers: { Authorization: `Basic ${ apiKey }` },
};
const { payload } = {
    amount
};
const { data } = await axios.post(`https://transaction-v1.api-eu.bambora.com/transactions/${ txnid }/capture`, payload, options);

I also tried making the request with included transactionoperations:

const options = {
    headers: { Authorization: `Basic ${ apiKey }` },
};
const { payload } = {
    amount,
    transactionoperations: [{ id: txnid }],
};
const { data } = await axios.post(`https://transaction-v1.api-eu.bambora.com/transactions/${ txnid }/capture`, payload, options);

I get the same error when trying to get transaction information:

const options = {
    headers: { Authorization: `Basic ${ apiKey }` },
};
const { data } = await axios.get(`https://merchant-v1.api-eu.bambora.com/transactions/${ txnid }`, options);

As I understand the documentation I'm doing everything right, but I can't get it to work.

After looking at Bamboras own implementation in PHP I can't see any issues with my code.

After looking at the Report Dashboard for a specific order in the URL doesn't match the ID I have saved in the database. The value of txnid returned on the Inline Checkout Authorize event doesn't seem to be accurate.

Answer 1

I was way off of where the problem was in our code. With help from the Bambora support and @Evelijn nudging in the right direction the problem is solved.

When sending the txnid from the client to the server the validation ensured that the value only contained digits. What I had missed was that it also changed it to a Number type.

The txnid is a String of 18 digits, javascript can handle numbers that are at most 17 digits big. When txnid was changed to a Number the last digit would be rounded to 0.

So 123456789012345678 would become 123456789012345680.

When I changed the validation not to cast txnid to a Number everything works.
