How can I send a file with a Graphql Mutation in insomnia.rest?

Question

I'm trying to upload an image with a graphql mutation to my server, how can I test this with insomnia.rest? the the Structured request for a Graphql Query doesn't show any field to add a file. Also, if this isn't posible with insomnia, what other alternative can I use to test something like this?

Answer 1

You'll want to use the "Multipart" request type. Then add the following values:

• operations: The graphql mutation in the format that is sent in the request, which should look something like below. (You can get this by using the GraphQL request option and switching to multipart form and then moving the values around).

{
 "query":"mutation UploadFile($file: File!) {\n  addResearch(file: $file)\n}",
 "variables":{ "file": null},
 "operationName":"UploadFile"
}

• map: { "File": ["variables.file"] }
• File: The file to upload. Click the dropdown on right beside the value input and choose "File" so that you can select a file.
