Delete items from Sharepoint list

[roland-daane]

Hi, I'm trying to delete all items from a SharePoint list, but keep getting this error:

412 Precondition Failed: {"odata.error":{"code":"-1, Microsoft.SharePoint.Client.ClientServiceException","message":{"lang":"en-US","value":"The request ETag value '' does not match the object's ETag value '\"d83ffc2b-6c9f-4db1-b0b1-1c1bfcfd4c16,1\"'."}}}

I found thet the headers needed to include:

    X-HTTP-Method: Merge

    If-Match: ETag

I first call:

_api/web/lists/getByTitle('B360__Issues')/items

Then in a loop

_api/Web/Lists/getByTitle('B360__Issues')/getItemById(ID from step 2)

I got the 2 headers in, but still getting the same error.....

hi Roland Daane ! here's an example call that worked for me with the headers called out:

Hi Sophat,

It runs now without errors.

For some reason the foreach loop just picksup 1 item whilt the Json output for step 2 contains a couple of hundred items.

It does delete that 1 record.

Oh and by the way: had a great discussion with our NL business and they're opening up to using Workato to connect with autodesk Construction Cloud....

here's the

step itself with the data outputs from the loop:
