Purpose
Document externally accessible endpoints into the 42Q MES system.
Usage
Unless otherwise specified all resource URI’s are designed to work with standard HTTP/HTTPS GET requests. The immediate focus of this set of API endpoints is retrieval of production data versus manipulation of said data.
Security
Typically each of these endpoints is secured via our API security package. This package requires each request to be signed by a registered client. Client registrations are provided to all approved API consumers. When authorization is enabled API calls require a properly formatted Authorization header in the HTTP/HTTPS request. The signature algorithms and format are described here though we recommend using pre-packaged libraries maintained and provided by 42q engineering teams.
API Resources
Currently, all of these resources return a standardized JSON result with three top-level attributes:
success: true or false
message: contains an error message if success is false
data: JSON subelement corresponding to the results of the call being made
The base URI for each MES API resource takes the following form:
https://HOSTNAME:PORT/mes-api/target_context
Sub Resources are identified from the base: path/to/resource[?arg1=value1&arg2=value2…] Note: Parameters can be sent in any order as part of the URL as only the name matters--not the location in the URL text.
The following top level resources are currently exposed:
Units Resource
Encapsulates endpoints associated with unit specific data, generally a specific unit serial number. The units resource exposes the following sub-resources assuming the {serialNumber} resource property identifies an existing serial number.

Work Instructions
Sample URI:
Response for actual document data {"data" : { "mime_type" : "application/pdf", "document" : "<imagine this is base 64 binary encoded data>", "document_type" : "base64" }, "success" : true, "message" : "This result demonstrates returning an actual document encoded in base64 text"}
Response for a url/link to a document {"data" : { "document" : "http://p88conduit1.sanmina.com:18005/ccr", "document_type" : "url" }, "message" : "This result demonstrates a response to a url instead of an actual document. Generally speaking this message is blank on success. Mime type not provided as it will be returned when accessing the url", "success" : true}
For both of these examples the message is populated even with success == true. Generally speaking this wouldn’t be the case but for the purposes of providing a concise explanation it seemed reasonable here.
API Data Import Instructions
There are currently two types of APIs:
- An API that is specialized for mass imports
- An API that is specialized for transactional data
Bulk Data Imports
For large amounts of data to be imported, there is an import API that is formatted in JSON. There is a function that wraps this data for security purposes, and the way that it is used will depend upon the client architecture.
- The URL for Nokia’s GOPS project will be similar to this: https://42qprtl1.42-q.com/mes-api/nokia_vendor_01/supplier/upstream/import
- “nokia_vendor_01” will be replaced by the client identifier. This will be used to know who is sending the data and what the target should be.
- A simple example follows. This example will record two components for each of the two serial numbers and move them to a specific location.
Request
{"units":[{"unit_id":"5S060000172","part_number":"MWKB82-0026-02-16","tracking":[{"ts":"2017-05-19 18:56:36-05","location":"ASSY"}],"components":[{"component_id":"MAC ADDRESS","ref_designator":"0103FAACE64A"},{"component_id":"MAC ADDRESS","ref_designator":"01164D2711D6"}]},{"unit_id":"5S060000173","part_number":"MWKB82-0026-02-16","tracking":[{"ts":"2017-05-19 18:56:36-05","location":"ASSY"}],"components":[{"component_id":"MAC ADDRESS","ref_designator":"0103FAACE64B"},{"component_id":"MAC ADDRESS","ref_designator":"01164D2711D7"}]}]}
Response
{"success":true,"message":"Successfully processed data for <2> unit(s)","data":[]}
Transactional Data
For data to be processed in the standard transactional model, the 42Q Conduit subsystem is employed. This allows for smoother integration and many additional functions compared to the restricted commands available in the bulk import API.
Again, this example does not have the architecture-specific security API, but that will be covered in another document dependent upon the client architecture.
- The URL for Nokia’s GOPS project will be similar to this: https://42qconduit1.42-q.com:18004/conduit
- The client_id is the same that is used in the previous API. The unit_id is the serial number or other identifier of the unit that is being processed.
- A simple example follows. This example will validate the status of the unit, add a comment, and move the unit to the next location in the route from the current “ASSY” workstation.
- The full list of commands and their parameters are available from this web service: http://42qconduit1.42-q.com:18005/ccr
Request
{"transactions":[{"commands":[{"command":{"name":"AddComment","comment_text":"This is a comment."}},{"command":{"name":"End"}}],"unit":{"unit_id":"5S060000169","part_number":"MWKB82-0026-02-16","quantity":1},"refresh_unit":true}],"source":{"client_id":"nokia_vendor_01","employee":"15475","password":"","workstation":{"type":"LOCATION","station":"ASSY"}},"version":"1.0","token":"","keep_alive":false,"single_transaction":false}
Response
The response will return both the status of the transaction and the device history record for the unit, including components, attributes, comments, and defects.
