Hi team,
There are some things that we would like to do with the download tool that currently are not possible:
1. use client side certificates to sign requests. This is a requirement for us in a project where we are interacting with the API of our customer's financial system. They provide us with a certificate and it is used to sign our requests, along with other authentication.Currently we have to use the external command tool to execute a powershell script using invoke-restmethod to do this interaction. I would much prefer to not have more tools in the chain.
Client certificates are described in the TLS 1.0 specification: https://tools.ietf.org/html/rfc2246 (page 43), and I believe them to be supported by cURL.
2. Multipart form-data. We have a number of workflows where we need to send multipart form data as part of a POST request. As this is not supported by the Download Tool, we have again used the external command tool to execute invoke-restmethod or invoke-webrequest in powershell. I don't know if modification of the Download Tool would be the best thing here, vs having either a dedicated tool for multipart form data, or having an HTTP POST specific tool that was able to handle multipart form data. What I envisage is something like the formula tool, with the ability to add an arbitrary number of cells, where we could use formula to either directly output a value from a column, synthesise a new value, or directly enter a static value). The tool would then compose this with boundaries between the parts, and calculate the content-size to add to the http request.
