Alphadoc: Construct API documentation that tells your API’s story

by Tom Johnson on Sep 17, 2023



A number of weeks in the past I discussed Alphadoc, a brand new software for publishing API documentation. The next is a Q&A with Daan Stolk, cofounder/CPO of Alphadoc. Within the following questions, Daan tells the story behind Alphadoc and what makes it distinctive from different API documentation instruments.

Be aware: This can be a sponsored put up.

Tom: Are you able to inform us why you began Alphadoc? Does your organization have an origin story? Was there something missing within the present API instruments within the market?

Daan: We beforehand constructed API merchandise in fintech and healthcare, and felt that instruments available on the market had been centered on the technical aspect of issues, whereas we wished to assist corporations get business success with a terrific developer onboarding. We didn’t assume that the world wants one other docs platform, however relatively a platform that helps to create an interactive onboarding expertise for APIs, SDKs, and codebases, which helps to create and enhance content material and makes the content material straightforward to grasp (by making it rather more visually interesting).

A big a part of the success from corporations like Stripe and Twilio is their concentrate on developer expertise from the very starting, and we wished to productize this and supply it to the market, to make it accessible to all corporations, even when they don’t have a devoted developer expertise (DX) crew. Thus far our focus has been totally on working with corporations with OpenAPI specs, however our newest function is now serving to corporations which have SDK’s assist clarify methods to use their merchandise as properly.

Tom: Trying on the current posts on the Alphadoc weblog, you are releasing main new options a number of occasions a month. Are you nearing an official launch date but for Alphadoc?

Daan: We’re delivery massive options month-to-month for the reason that begin of this yr. Along with design companions we have now formed the product to the purpose the place it’s at this time, and we intend to open up for wider availability on the finish of September.

Tom: What’s the new Code-Walkthrough software about? Additionally, there’s additionally a sequence diagram builder?

Daan: We have now already constructed a whole platform for displaying REST APIs and making guides based mostly on stated APIs. Corporations had been coming to us which have extra than simply REST APIs. They should mix documentation for SDKs and REST APIs. We’ve launched a brand new function known as Code-Walkthroughs, which permits for highlighting of code and creating step-by-step guides with a number of information as properly.

Code Walkthrough

We additionally robotically generate diagrams for REST API “chains.” To create REST API guides, you add endpoint blocks to a tutorial. You’ll be able to configure endpoint blocks to solely show the parameters you need to show (see the next screenshot).

To create a series, add two (or extra) endpoints in a tutorial collectively by indicating {that a} worth within the response of 1 endpoint ought to be used within the request of the following endpoint. The diagram that we generate shows an information relationship which represents the chain you simply made. Any updates you make to the chain will robotically replicate within the diagram.

Within the diagram extra info is made accessible as you click on via the blocks. Each the endpoints and the diagram robotically replace if a brand new model of the API spec is up to date.



We’re releasing a brand new function quickly—Sequence diagrams. It is possible for you to to create sequence diagrams by rapidly clicking collectively the lifelines (vertical strains) and messages (these will symbolize API calls), and also you get extra flexibility in comparison with the generated diagrams.

Sequence diagrams

So, one model of the diagrams is robotically generated if you create a tutorial with API chains. The opposite model is a sequence diagram that has extra flexibility.

Tom: I noticed that change logs are robotically created. How is that this being completed and the way are you integrating AI options?

Daan: We certainly assist robotically creating comparisons everytime you add a brand new model of your OpenAPI spec to our platform. Our AI performance is a chat interface constructed on prime of OpenAI’s API—we centered on serving to builders get a solution to their query as rapidly as attainable. We use all of the content material that’s added to the platform, which may be written guides, code, APIs, and SDKs.

The function remains to be experimental however response to this point has been nice. The person can ask any query about your content material, and we’ll reply. All knowledge submitted to OpenAI has been opted out of coaching their fashions.

AI functionality

Due to the character of technical documentation and the necessity for it to be appropriate, we constructed it in a method that minimizes hallucinations (AI making up issues). Sooner or later we’ll be utilizing the suggestions derived from person habits to create content material solutions. When a number of folks ask related questions, it probably must be clarified in your docs.

Utilizing insights to enhance the documentation remains to be one thing we’re engaged on (and are eager on getting suggestions!). We’re additionally very conscious of privateness issues when capturing search queries completed by builders and can introduce a compliant method for our customers to research these queries sooner or later.

A humorous aspect impact is that with the current explosion of LLMs, the edge to write down code and construct software program and integrations is lowered considerably, and that makes it much more necessary to have a developer onboarding that’s comprehensible for each seasoned and citizen builders.

Tom: Concerning assist for OpenAPI, lots of instruments say they assist OpenAPI however may not assist a number of the extra superior specification options. Are you able to discuss a bit about why Alphadoc has deep assist for the OpenAPI spec? I believe many tech writers may not even concentrate on tooling limitations for some schemas till they encounter them.

Daan: And the identical goes for us—we had been solely made conscious of the depth of our assist for the OpenAPI spec after we encountered customers that attempted and examined numerous different options and that none of them had full assist for a number of the choices within the spec. OpenAPI has built-in ideas to mix and reuse schema’s throughout your complete specification (Google “OpenAPI polymorphism” to be taught extra!). The commonest occurrences are utilizing anyOffs, oneOffs, and allOffs.

From a software vendor perspective this introduces complexity which we’ve determined to deal with head on. If in case you have used any of those ideas in your OpenAPI file you’ll see it correctly rendered all through the platform, all the way down to code snippets updating based mostly on what you’ve chosen.

One other good instance of a deeper degree of assist is our capacity to show self-referencing schema’s, also referred to as round references. When a schema references itself, it might probably break a number of the common open supply OpenAPI instruments.

There are nonetheless many OpenAPI ideas we have now but to deal with however see a ton of worth in offering assist for all of them as time goes on.

A few of our customers have actually massive APIs with hundreds of endpoints—a scale our platform simply helps. When it comes to efficiency, we made a ton of enhancements to supply a handy guide a rough expertise.

Tom: How do you allow collaboration throughout tech writers, product managers, builders, and entrepreneurs? Do they use Git with model management to collaborate? Or does Alphadoc present different collaboration workflows? How do you stability strong instruments with easy interfaces and workflows that much less technical folks can work together with?

Daan: We incessantly work with corporations that need to make it simpler for folks to collaborate internally on developer docs. We began working with a versatile WYSIWYG editor. Markdown may be typed within the UI and is instantly rendered. We’re additionally providing engineers methods to robotically push new variations of their API spec to our platform through Git.

One of the vital widespread factors of suggestions we’ve acquired was that writers need to handle all of the content material (not simply the API) in a Git workflow. We’re glad to say that earlier than the top of the yr we’ll assist docs-as-code workflows on prime of the browser-based editor.

Right this moment we additionally assist embedding our parts into different options or platforms, which makes Alphadoc modular and accessible together with different content material platforms. Considered one of our customers has already embedded a tutorial immediately into their utility to assist builders instantly see methods to use their API after they have created their API key.

Tom: You talked about that Alphadoc helps complicated storytelling for various ranges of technical customers. Storytelling is not a function I generally see promoted in API instruments. Are you able to speak about what you imply by storytelling and perhaps present an instance?

Daan: At Alphadoc, after we speak about “storytelling,” we imply extra than simply documentation; we’re centered on creating an interactive and interesting narrative round your APIs and SDKs. It’s about guiding customers via the functionalities and potentialities of your product in a coherent method. Our platform permits you to configure every API endpoint, work with variables, and set up chains of endpoints.

This method empowers corporations in numerous industries, reminiscent of Ecommerce and Fintech, to successfully convey their product tales. Corporations within the Ecommerce and Fintech trade, for instance, have many use instances of their APIs the place knowledge (IDid’s) must be carried over between endpoints (carrying over knowledge between API calls). Additionally they usually have endpoints which can be very versatile, which makes it troublesome for them to clarify all attainable situations on methods to use them.

The tutorials and diagrams in Alphadoc permit you to utterly configure every endpoint if you add it to a web page, work with variables (assume Postman), and chain up endpoints. When the whole lot has been configured, we offer useful code snippets for every API name and robotically generate interactive diagrams that show the connection between all of the steps. The developer who’s integrating can check out API calls with reside knowledge.

To see this idea in motion, discover our personal documentation at docs.alphadoc.io, the place you’ll be able to witness how we rework technical documentation into an interactive storytelling expertise.

Tom: How can folks be taught extra about Alphadoc and take a look at it out?

Daan: To start out constructing your docs & DX with Alphadoc, please fill out the sign-up kind or go to our web site at alphadoc.io. We’ll evaluate your request for entry inside 1 enterprise day. If granted entry, you’ll be able to add your OpenAPI spec and simply create a compelling developer expertise.
