API for Beginners
11 likes9,136 views
This document provides an overview of APIs and how they work. It begins with basic API concepts and definitions, then demonstrates how APIs are used by having programs interact with applications to access structured data without direct human interaction. It provides examples of common API uses for maps, login/authentication, payments, messaging and more. It also introduces the concept of webhooks which allow applications to "call" other services when data is available, rather than requiring the other service to periodically check via API calls. Overall it serves as a high-level introduction to APIs and webhooks for beginners.

- 22. Let’s play with Facebook graph API
- 24. Maps
- 25. Maps
- 26. Google Maps API
- 27. Login
- 28. Aggregators
- 29. Payments
- 30. Twilio API
- 31. UBER Shares of Twilio (NYSE:TWLO) have more than quadrupled from its IPO price of $15.
- 32. Favspot
- 34. As a developer,
- 35. I want to show venues of next gigs in town on a map
- 36. Timeout content manager will enter venue addresses
- 37. Timeout content manager doesn’t know GPS coordinates of venues
- 38. There’s an API for that
- 40. 10 Downing St, London
- 41. 10 Downing St, London { "location" : { "lat" : 51.5034066, "lng" : -0.1275923 } } This is called JSON
- 42. How does it work?
- 43. API call is an HTTP request https://maps.googleapis.com/maps/api/geocode/json?address=10 Downing St, London
- 46. Are we done?
- 47. We should now integrate the Google Maps API
- 49. I want the app to send text messages if a gig is cancelled
- 50. Let’s look at some code
- 51. Step 1 - Sign up to Twilio
- 52. Step 2 - Fetch credentials
- 53. Step 3 - Write some ruby require 'twilio-ruby' account_sid = 'AC__________' auth_token = '_____________' client = Twilio::REST::Client.new(account_sid, auth_token) client.messages.create( from: '+336123456789', to: '+3370000000000', body: 'Hi buddy, you should attend Le Wagon!' )
- 54. Step 4 - Run code
- 55. Your program sent a text!
- 57. Don’t call us, we’ll call you
- 59. Webhook vs API call API My app API Call
- 60. Webhook vs API call API My app WEBHOOK API Call
- 61. EXAMPLE
- 62. Typeform, please call notify me as soon a new member applied Webhook
- 63. Typeform to capture leads Slack for my sales team Lead Management
- 64. API Service B exposes methods to read, create or update data
- 65. WEBHOOK Typeform pushes data as soon as available API Slack exposes methods to read, create or update data
- 67. Demo
- 68. When you’ll hit Zapier's limit, come learn to code at Le Wagon!
- 69. Thank you!
