X-External-Context-ID in "Update an issuance for an ILC"

Hello


I'm currenty testing the "Update an Issuance for an Import Letter Of Credit" API in "Import Letter of Credit" B2B Collection, but I always get the following message :


"Unable to decode the supplied X-External-Context-ID header. The X-External-Context-ID should match the value sent by the corresponding event notification."


How can I get an X-External-Context-ID or what does it look like ?

Hello El Houssaine Myaz,


Yesterday we have published new version of postman collection, please redownload collectionand test again if you are facing issues. Please note that this API is using webhooks, in order to receive proper responses edit your application containing Import Letter of Credit API and in Events Tab provide this URL https://subscriberwebhook.azurewebsites.net/

Depending on your postman configuration you might need to change pre-request script in Update an issuance of an Import Letter of Credit request:

var delay = pm.environment.get("getIdDelay");
var limit = pm.environment.get("getIdLimit");
var url = pm.environment.get("getIdBaseUrl") + "/import-letter-of-credit/issuances/" + pm.environment.get("id")

to:

var delay = pm. collectionVariables.get("getIdDelay");
var limit = pm.collectionVariables.get("getIdLimit");
var url = pm.collectionVariables.get("getIdBaseUrl") + "/import-letter-of-credit/issuances/" + pm.environment.get("id")


Best Regards,

Hello Szymon,

I downloaded the last version of the API, then I provided the webhooks URL in the events tab of the application:

And I changed the pre-request script in Postman:

Now, it takes even more time to get the response, and I get the same error as before :

In Postman Console, I first get the following (many failed attempts to fetch external context id). Here is an example:

err1.png


I don't know if getting "undefined" at the end of the URL is normal, I normally add the master ID to the URL like this :


{ {APIMUrl}}/{ {context-root}}/import-letter-of-credit/issuances/32079


Then, under that, I get the following in the console:

Hello,

Have you send Issue an Import "Letter of Credit" and "Issue an Import Letter of Credit for PUT Request" request first? Did it succeeded?

It is mandatory to send these requests first as they are setting up variables used later in Update request both in URL and in Pre-request scripts, and updating the status of letter of credit so it can be updated with PUT request.

To sum up correct workflow is:

1. Send Issue an Import Letter of Credit

2. Send Issue an Import Letter of Credit for PUT Request

3. Send Update an issuance of an Import Letter of Credit

Best Regards,

Szymon
