MESH Endpoint Lookup Service - help please

My last experience with the wonderful world of NHSD certs ended up with a call to SA-Service desk. They answered and fixed pretty quickly.

As I say, I’m pretty confident that the problem isn’t certificate-related. I’ve contacted the NHS Digital Platforms Support Desk, who have kindly referred me to the specification I am already using :slight_smile:

To be fair, they also invited me to get back in touch if I was still stuck - which I have done - but I thought I’d try crowdsourcing some suggestions whilst waiting for their reply.

Cheers,

Nigel

How sure are you that the ODS code you are trying to reach is registered with a MESH endpoint for those workflow IDs? The governance around changes to MESH endpoints has been patchy in the past with the result that there are inaccuracies in the underlying database.

This is still N3 only? No opentest

I’ve tried various ODS codes:

  • those of a number of the GP Practices we want to send documents to, with various Workflow IDs, inc TOC_FHIR_OP-ATTEN (which the NHS Digital Interop Team recommended we use for communicating our messages to GP systems), TOC_OUTP_ATT_DMS and GP2GP
  • our own - we’ve recently been allocated a MESH mailbox by NHS Digital specifically to send Transfer of Care messages, such as Outpatient Attendance;
  • the example given in the spec (ODS Code: X26, Workflow ID TOC_AE_DMS.

All fail in exactly the same way - “404 Not Found”.

I haven’t heard of “opentest”.
I have some test MESH accounts and the client certificates for using NHS Digital’s Integration Test environment, but they didn’t supply the API keys/certs, and there is no mention of the MESH Endpoint Lookup Service in that environment - although I’ve now been told it is there, so I’ve just asked for the API keys/certs. Meantime, as it was such a simple API, I thought I’d test it worked on Live, as I already have all the keys and certificates - only to find it doesn’t :frowning:

Hi Nigel. We helped create MESH and have written several integrations for it. Tricky to understand what the problem might be over chat but if you really get stuck feel free to get in touch and we might be able to free up one of our DevOps engineers to help.

Thanks for the offer Joseph. It’ll be next week before I have the opportunity to have another chance to try anything on this again, but if you have the ability to call the API and can tell me exactly what URL you used (including ODS Code and Workflow ID), and the response you got, that will enable me to test an exact call that someone else can successfully make.

Cheers,

Nigel

On a side note. Does anyone know why MESH endpoint lookup wasn’t implemented within Spine Directory Service? So when you run the queries to lookup up services provided by organisation (ods = 123).
So for sending documents to GP’s you don’t want to query one to find the unstructured endpoint (GP Connect Send Task) and then the other for structured (Transfer Of Care)

SDS is currently holding http (/restul and Hl7v3) delivery addresses and MESH mail delivery addresses. In theory to work how to send it involves two separate systems from NHS Digital which is not ideal.

both document formats are going to use HL7 FHIR… but may again differ on the FHIR Message ‘envelope’.

Hi,
Looking at the same. Noticed NHSD documentation suggest the following address if using the API
https://mesh-sync.national.ncrs.nhs.uk/messageexchange/endpointlookup/odscode/workflowid

This gets a response…

it is only me or the link won’t open? really wanted to check it out. maybe site changed? can you post an updated link? thanks

Are you testing through a HSCN/TN connection? You’ll need this and all the relative certs…

I think mesh is now available on opentest. Has anyone tried it

And so doesn’t need HSCn network

You need to VPN to the Opentest environment instead of HSCN - not tried it as I have access to a HCSN connection. Try applying for VPN access and let us know how you get on…

will try your method and check if it works, hopefully it would help with my project.

Does any know the API endpoints for mesh on opentest?

I’m wanting to use the API (MESH API · Apiary) to send documents.

thanks

Have you tried the same ones documented for HSCN access? Possibly with OpenTest you are just VPN’ing into the same environment HSCN gives you access to

I believe it’s https://192.168.128.11/messageexchange but haven’t had time to check.
