When I am sending a single observation then it is getting created but for multiple observations it is throwing an error 500.
For single observations my query is - TYPE- POST URI - /openmrs-standalone/ws/rest/v1/obs BODY- {
“concept” : “5086AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA”, “person” : “610b0696-7529-4b4a-b65b-37336a75962a”, “obsDatetime”: “2017-07-24T15:33:49+05:30”, “encounter”: “3bc0672d-ebc6-4e65-aae1-8a1d4de759bf”, “value” : “90” }
For multiple I am sending TYPE- POST URI - /openmrs-standalone/ws/rest/v1/obs BODY- [{“concept” : "5089AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA ", “person” : “610b0696-7529-4b4a-b65b-37336a75962a”, “obsDatetime”: “2017-07-24T15:33:49+05:30”, “encounter”: “3bc0672d-ebc6-4e65-aae1-8a1d4de759bf”, “value” : “99” }, { “concept” : “5090AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA”, “person” : “610b0696-7529-4b4a-b65b-37336a75962a”, “obsDatetime”: “2017-07-24T15:33:49+05:30”, “encounter”: “3bc0672d-ebc6-4e65-aae1-8a1d4de759bf”, “value” : “185” }] The error is here [https://pastebin.com/uBaJmZa9](https://pastebin.com/uBaJmZa9)

Have you considered the encounter resource having multiple observations?

The `obs` resource does not support posting multiple obs.
As Daniel says, the encounter resource would let you create multiple obs (in an encounter).

@darius and @dkayiwaIs there a way of creating sessions in openMRS. I mean to say that I am sending too many REST request with username and password. Is it possible that some of my REST POST queries are not working because there’s already the user logged in. If I could somehow create a session through REST and then send all the request and finally close the session.

See the Authentication section here: [https://wiki.openmrs.org/x/P4IaAQ](https://wiki.openmrs.org/x/P4IaAQ) (Note that this is the first google hit for “openmrs rest session”)
Perhaps the way you’re making REST calls using Mirth does not maintain a session?

Thanks @dariusI found out that for sending REST request one “ **needs** ” to send a request header of **Authorization:Basic** = **username:password** or one has to set a cookie of sessionId. Eg- URL: [http://localhost:8083/openmrs-standalone/ws/rest/v1/visit](http://localhost:8083/openmrs-standalone/ws/rest/v1/visit) METHOD: POST
[HEADERS] Set-Cookie: jsessionid=C17C12C50D5C194E2487982F08C4BAEB Authorization:Basic: YWRtaW46QWRtaW4xMjM=
[PARAMETERS]
[CONTENT] { “patient”:“c342807d-fc65-4de1-983e-424c4add487d”, “visitType”:“7b0f5697-27e3-40c4-8bae-f4049abfb4ed”, “location”:“bf38803c-b24c-4d54-bd8d-15fe17a79d0d” }
