Business rule to send attachment to 3rd Party Tool via REST

[Neeraj Sharma10]

Hello Experts,

How can we configure Outbound Rest message to send attachment to 3rd party(cloudplus) which later can be used in business rule?

Or is there other way of writing business rule for the same.

Do we need to encode it into Base64 before sending?

I am bit confused.
Any Help would be appreciated.

Thanks

Hi Neeraj,

In addition to what Jarod answered, you can find this link useful for help on RESTMessageV2

Unexpected behavior from remote host: Unbuffered entity enclosing request can not be repeated.

finally i am able   to successfully send   attachment to 3rd party and viceversa via rest.

Points to Remember.

Sending attachments   (serviceNow to 3rd party)

1. Outbound Rest message- Need to ask for a endpoint of the 3rd party. Configure HTTP headers If any.

2. Use this Rest message in the business rule to send attachments

                  a. Call the rest message and simply send the binary content of the attachment to the request body using function request.setRequestBodyFromAttachment('<attachment sys_id>');

(RESTMessageV2 - setRequestBodyFromAttachment(String attachmentSysId)   )

  Screenshot of the business rule

And you will see Magic happens.

Receiving attachments (3rd party to serviceNow)

1. Go Rest API explorer > select Attachment API in API name and explore all the APIs available (Get, Post, Delete)

For are two ways of making Post request :-

a) https://yourinstance.service-now.com/api/now/attachment/file

b) https://dev33253.service-now.com/api/now/attachment/upload

table_name = Table name ( incident for above case)

table_sys_id = Unique Id of the record to which attachment needs to be inserted.

file_name = name of the attachment.

In HTTP header you need to send Content-Type Also (Not mandatory but always good to give).

Postman Screenshots

Hope this will be helpful.

Hi Neeraj,

Can you please share   the details like what method are you using, is it 'Attachment' in REST outbound?

I dont see this method in REST.

[Neeraj Sharma10]

Hi Kumaran,

I am using Post method.

But again it is dependent on 3rd party endpoint.

Thanks

Please mark answer as correct or helpful based on the impact.

Thanks Neeraj.

What are all the informations need to send other than attachment sys_id.

I tried to call REST without any parameters, passed method and endpoint in Business rule itself.
