Installation

Requirements

Before installing, make sure your environment meets the following requirements:

Requirement Details
Board ESP32 (any variant: ESP32-S2, S3, C3, etc.)
IDE / Core Arduino IDE 1.8.x/2.x or PlatformIO
ESP32 Arduino Core v2.x or later
Dependencies None — no external libraries required
  1. Open the Arduino IDE.
  2. Go to Sketch → Include Library → Manage Libraries....
  3. Search for ESP32-HTTP-Client.
  4. Click Install on the result by Pedro Fonseca.

Method 2: PlatformIO

Add ESP32-HTTP-Client to the lib_deps section of your platformio.ini project configuration file:

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
lib_deps =
    PedroFnseca/ESP32-HTTP-Client@^1.4.0

Alternatively, install it via PlatformIO CLI:

pio pkg install --library "PedroFnseca/ESP32-HTTP-Client"

Method 3: Manual Installation

  1. Download the latest release ZIP from GitHub.
  2. In the Arduino IDE, go to Sketch → Include Library → Add .ZIP Library....
  3. Select the downloaded ZIP file.

Alternatively, extract it directly into your Arduino/libraries/ folder:

Arduino/
└── libraries/
    └── ESP32-HTTP-Client/
        ├── src/
        │   ├── ESP32HTTPClient.h
        │   ├── ESP32HTTPClient.cpp
        │   ├── RestRequest.h
        │   ├── RestRequest.cpp
        │   ├── RestTypes.h
        │   └── BufferedStreamReader.h
        ├── examples/
        ├── library.properties
        └── ...

Verify Installation

After installing, verify by loading one of the built-in examples:

File → Examples → ESP32-HTTP-Client → RestCrud

Upload it to your ESP32 (with your WiFi credentials filled in) and open the Serial Monitor at 115200 baud.
