Re: Updating a resource causes: Status: 412 Precondition Failed
Syed,Jenni
Hi. First: your posts are getting marked as spam, which causes them to go into holding. I’m responding on this one via the old email notification because it sounds like there’s been some confusion around posts being deleted (we assumed you were deleting them since you didn’t see them immediately). If something goes to spam, just give it some time and it will be released by a moderator.
As to your question:
In your error post below, you can see the response:
“> no If-Match or invalid If-Match header provided”
To update, you must send the If-Match[1] header with the version of the AllergyIntolerance that you’re updating. This can be found in the AllergyIntolerance.meta.versionId field when you read it. You then take that value and create an If-Match looking like this:
If-Match: W/”[versionId]”
If the resource has been updated since you read it by someone else, you’ll get a 409/conflict – your code will need to handle this gracefully.
Our doc [2] currently states it’s the allergy id, which is incorrect and quite confusing. We’ll get that updated.

Subject: Updating a resource causes: Status: 412 Precondition Failed
I read the list of Allergies of a patient. I have the option to create or update an existing record. The create is working fine but on update I am getting an error below. Is there anything that I am missing? The request/response headers
are below.
