Batch request - Dynamics CRM

Question

All,

I am trying to implement a batch request to Dynamics CRM with the following source code:

public async Task HttpPatchC         


        

Answer 1

I think your request is wrong. You must build the request Body EXACTLY like defined by Microsoft

This means the Blank lines must be there at the right place all the attributes must exist in the body (like "--changeset_XXX" for example) and as I see you dont meet this requirements.

I just build a Request in Postman against my CRM and it worked:

---

URL

https://yourTenant.api.crm.dynamics.com/api/data/v8.0/$batch

---

Headers

OData-MaxVersion:4.0
OData-Version:4.0
Accept:application/json
Authorization:Bearer aVeryLongStringTokenHere
Content-Type: multipart/mixed;boundary=batch_1234567

---

Body

--batch_1234567
Content-Type:multipart/mixed;boundary=changeset_555666

--changeset_555666
Content-Type:application/http
Content-Transfer-Encoding:binary
Content-ID:1

POST https://yourTenant.api.crm.dynamics.com/api/data/v8.0/accounts HTTP/1.1
Content-Type:application/json;type=entry

{name: 'BatchJobTest788'}
--changeset_555666
Content-Type:application/http
Content-Transfer-Encoding:binary
Content-ID:2

POST https://yourTenant.api.crm.dynamics.com/api/data/v8.0/accounts HTTP/1.1
Content-Type:application/json;type=entry

{new_name: 'BatchJobTest348'}
--changeset_555666--
--batch_1234567--

---

Additional Remarks:

• The Content-Type of your Header holds your BatchId
• The Content-Type of your Batch holds your ChangesetId (if it is a change to data)
• Before starting to programm REST calls try to define them in a REST tool like POSTMAN and make them work. Then build the working request in your code.
