@sebastián-cisneros In static:api.routes, you'll want to call controllerHelpers.setupAPIRoute to mount the route to the appropriate /api/v3/plugins mount point.
You can see an example of how we do it in the quickstart plugin
@Doppy add it to your plugins package.json
"dependencies": {
"sparkpost": "1.3.6"
}
Alternatively, just install it with the --save
flag and it will pin the current version in your package.json
npm install --save sparkpost
