Installation¶

Requirements¶

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

Requirement	Details
Board	ESP32 (any variant: ESP32-S2, S3, C3, etc.)
Arduino IDE	1.8.x or 2.x
ESP32 Arduino Core	v2.x or later
Dependencies	None — no external libraries required

Method 1: Arduino Library Manager (Recommended)¶

Open the Arduino IDE.
Go to Sketch → Include Library → Manage Libraries....
Search for ESP32-HTTP-Client.
Click Install on the result by Pedro Fonseca.

Method 2: Manual Installation¶

Download the latest release ZIP from GitHub.
In the Arduino IDE, go to Sketch → Include Library → Add .ZIP Library....
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 → SimpleGET

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