Information is power and monetisation of data is a common theme in the corporate world today. One of the common use-cases for the API Platform is to leverage corporate services and data and provide it to a broader internal and external development community. Control is kept in-house through security, policies, throttling, etc, but it dramatically increases the pool of developers working with our services.
API Platform is a great tool for this, but if I’m going to expose services to a developer community, I don’t really want to have an Oracle branded developer portal exposed.
fortunately, rebranding the developer portal is as easy as one, two, three!
- Build a configuration file with customisations
- Run a curl command
- Have a coffee break
Ok… so it is as easy as one, two, but I like having a coffee break when I’m able!
The API Platform has three basic API services to customize the portal, get, set (post) and delete. The documentation can be found here:
The delete operation will remove all custom configurations, so this is an easy way to reset the portal in case you make a mistake.
curl http://mydevportal/apiplatform/developers/v1/customization/configuration -X DELETE --header "Content-Type: application/json" -u weblogic:welcome1
This gets things back to the default look and feel:

So first we need a configuration file. It is fairly easy to build the json file following the documentation, but here is a sample: (config-cb.json)
{
"branding": {
"vendor": "Peanuts",
"product": "Peanuts API Platform Services",
"product_short": "Peanuts API Platform CS",
"title": "Developer Portal",
"logo": {
"url": "http://www.iowacitycommunitytheatre.com/wp-content/uploads/Wp-charlie-brown-banner.png",
"width": "auto",
"height": "17px",
"alignment": "baseline"
},
"login": {
"logo": {
"url": "https://upload.wikimedia.org/wikipedia/en/2/22/Charlie_Brown.png",
"width": "185px",
"height": "326px"
},
"splash": "",
"productLogo": "http://www.stickpng.com/assets/images/5853c45aec0c270fc2f62df4.png",
"background": {
"desktop": "https://i.ytimg.com/vi/055wFyO6gag/maxresdefault.jpg",
},

}
},
"css": {
".oap-login-product-title-1": {
"font-family": "\"Comic Sans MS\",\"Comic Sans\",cursive",
"color": "#FF0000"
},
".oap-login-submit-button": {
"text-indent": "-9999px",
"line-height": "0",
"background-color": "#ff0000"
},
".oap-login-submit-button::after": {
"content": "\"Kick Ball\"",
"border": "5",
"text-indent": "0",
"display": "block",
"line-height": "initial",
"background-color": "#00ff00",
"color": "#000000"
}
}
}
Note: There are many settings available for configuring things like graphics and logos. If you want to make lots of changes, you are able to overide the CSS. I used my browser’s inspect feature to see what to change in the CSS to update a few fonts and button colours.
Once the config file has been created, run a curl command to install it.
curl http://mydevportal/apiplatform/developers/v1/customization/configuration -X POST -d @config-cb.json --header "Content-Type: application/json" -u weblogic: welcome1
Once this has executed, the login screen looks something like this:

The portal can also be customised after login as well in the same way.
