I am new to the MESH\ITK3 standards so I’m wondering if I can seek some advice.

Our outpatient letters come to us from the 3rd part system as a PDF.  We need to send this to our GP practices using the MESH client.  Using FHIR I think we can achieve this using the workflow TOC_FHIR_OP_ATTEN.

What options are available to send a PDF? 

As a side note, I think Kettering XML may be out of the question as the TOC_OP_ATT_DMS workflow is used on another mailbox that is already being used by another system.

I believe that workflow id refers to this specification https://digital.nhs.uk/services/interoperability-toolkit/developer-resources/transfer-of-care-specification-versions
and **Outpatient Clinic Letter**.

This is a FHIR Document which means a HTML document plus structured clinical content. 

I don't know what the workflow id for kettering is I'd expect TOC still means transfer of care.

If you have a PDF document, the only option I believe is Kettering over MESH.

Thank you.  I think that has just confirmed my that at thought might be the case.

Hi @mayfield.g.kev 

I'm currently developing a MESH API interface to send PDF reports, but I can't seem to get the MESH API to send the PDFS.

What I have tried, which have failed.

1. Simple PDF converting to Base 64 and sent in body with content-type of application/pdf
2. Kettering.  I've taken a example from number of different source online (plus a vision document) and sent the Kettering XML in the body with a content-type of "application/octet-stream"

Di you get your service to send a PDF and if so how?  If you could help or point me to some useful resource, that would be great.

Thanks
