Onboarding Guides

Who this is for

• API engineers and technical writers responsible for first-run developer experience.
• Backend engineers adding or improving Quickstarts and setup guides.
• DX/DevRel folks building sample apps, Postman collections, and SDK snippets.

Prerequisites

• Basic knowledge of HTTP APIs (methods, status codes, headers).
• Familiarity with API keys or OAuth2.
• Ability to run cURL or a simple script in one language (e.g., JavaScript or Python).

Why this matters

Great onboarding guides reduce support load and increase activation. In an API Engineer role, you will:

• Ship a Quickstart that gets a new developer to their first successful request in minutes.
• Show clear steps for auth, environment setup, and error handling.
• Provide code snippets (cURL + 1–2 SDKs) and a minimal, working example.
• Prevent common mistakes (wrong keys, missing headers, sandbox vs. production mix-ups).

Concept explained simply

An onboarding guide is a short, opinionated path from “hello” to the first working API call (and a next step). It removes guesswork with exact commands, sample data, and clear outcomes.

Mental model

Think of it like a guided tunnel:

• Entrance: prerequisites and keys.
• Lights on the floor: exact commands and code to copy-paste.
• Green sign: a visible success output.
• Exit: the most common next action (e.g., create a resource, subscribe to a webhook).

Anatomy of a great onboarding guide

• Short intro: what the API does and what you will accomplish.
• Prerequisites: account, keys/tokens, supported environments.
• Setup: install tools, set environment variables.
• Auth: exact header or token usage, with a working example.
• First request: copy-paste snippet + expected response.
• Common errors: show the message and how to fix.
• Next steps: one clear path (create X, listen for webhook Y).
• Support note: where to ask questions (email/forum/chat). No links needed here; your product UI supplies them.

Worked examples

export NOTES_API_KEY="sk_test_123"

curl -s -H "Authorization: Bearer $NOTES_API_KEY" \
  https://api.example.com/v1/me

{
  "id": "user_abc",
  "email": "dev@example.com"
}

npm install @example/notes

import Notes from '@example/notes';

const client = new Notes({ apiKey: process.env.NOTES_API_KEY });

async function run() {
  const note = await client.notes.create({ title: 'Hello', body: 'First note' });
  console.log(note.id);
}

run().catch(console.error);

note_123

python3 -m pip install flask
cat <<'PY' > app.py
from flask import Flask, request
app = Flask(__name__)
@app.route('/webhook', methods=['POST'])
def webhook():
    print('event:', request.json)
    return '', 200
app.run(port=3000)
PY
python3 app.py

curl -X POST -H "Authorization: Bearer $NOTES_API_KEY" \
 -H "Content-Type: application/json" \
 -d '{"title":"Webhook test","body":"Hi"}' \
 https://api.example.com/v1/notes

Exercises

You can complete these without special tools. The test at the end is available to everyone; only logged-in users will have saved progress.

1. Exercise ex1: Draft a one-page onboarding guide for a fictional Notes API. Include prerequisites, auth, first request, expected output, and a troubleshooting section.
2. Exercise ex2: Convert a cURL Quickstart into SDK snippets (Node and Python) and specify how a user would run them locally with environment variables.

Common mistakes and self-check

• Too much theory up front. Fix: keep intro to 2–3 sentences; move details to references.
• No visible success signal. Fix: print IDs or counts; show a real JSON response.
• Ambiguous auth. Fix: show exact header with placeholders and an environment variable example.
• Mixed environments. Fix: label endpoints and keys as test/sandbox vs. production.
• Missing error guidance. Fix: include 401/403/429/422 examples with remedies.

Practical projects

• Build a "First 5 Minutes" guide for an internal microservice API, including cURL + one SDK and a Postman collection.
• Create a webhook quickstart end-to-end: local server, signature verification, retry notes.
• Write a "Going to Production" page: rate limits, pagination, idempotency, and monitoring tips.

Learning path

Next steps

• Instrument time-to-first-success and track where users drop off.
• Add language tabs for your top SDKs based on user demographics.
• Expand with production best practices after the Quickstart.

Mini challenge

Rewrite a 5-paragraph intro into two sentences focused on the outcome and what the user will build. Keep it under 30 words. Bonus: include a visible success metric (e.g., "see note ID in output").
