How to utilize the AdditionalInfo field for conditionDesccriptor

[nolanjaylefler]

myitem["Item"]["ConditionDescriptors"]["ConditionDescriptor"].append({'Name': '27501', 'Value': row[12]})
myitem["Item"]["ConditionDescriptors"]["ConditionDescriptor"].append({'Name': '27502', 'Value': row[13]})
myitem["Item"]["ConditionDescriptors"]["ConditionDescriptor"].append({'Name': '27503', 'Value': '87651234'})

I'm using the code above to add the correct Professional Grader and Grade, however the last line, which is supposed to provide the Certification Number, is coming back with this error:

AddItem: Class: RequestError, Severity: Error, Code: 21920352, Condition descriptor value 87651234 is not valid for condition descriptor 27503. Condition descriptor value 87651234 is not valid for condition descriptor 27503., Class: RequestError, Severity: Error, Code: 21920357, Valid information is required for descriptor Certification Number (27503). Descriptor information sent as NULL. Valid information is required for descriptor Certification Number (27503).

I need advisement on how to populate this field, because what I'm doing is not working.

The certification number is not a name/value under ConditionDescriptor. Instead, it is called "AdditionalInfo" under ConditionDescriptor. So I think your last row might be something like:

myitem["Item"]["ConditionDescriptors"]["ConditionDescriptor"].append({'AdditionalInfo': '87651234'})

See a Trading API example here:

    <ConditionDescription> string </ConditionDescription>
    <ConditionDescriptors> ConditionDescriptorsType
      <ConditionDescriptor> ConditionDescriptorType
        <AdditionalInfo> string </AdditionalInfo>
        <Name> string </Name>
        <Value> string </Value>
        <!-- ... more Value values allowed here ... -->
      </ConditionDescriptor>
