## <a name="config"></a>Configuration

All configuration files can be in YAML or JSON format.

### <a name="main-config"></a>1) Main configuration

When executing the app it by default looks for a `config.yaml` file in the current directory. If it does not exist it will be created automatically.

The configuration file to be used can also be specified using the `--config <PATH>` command line parameter. It must point to a YAML or JSON file.
Valid file extensions are `.json`, `.yaml` and `.yml`

The following parameters can be configured:

```yaml
# yaml-language-server: $schema=https://raw.githubusercontent.com/Second-Hand-Friends/kleinanzeigen-bot/refs/heads/main/schemas/config.schema.json

# glob (wildcard) patterns to select ad configuration files
# if relative paths are specified, then they are relative to this configuration file
ad_files:
  - "./**/ad_*.{json,yml,yaml}"

# default values for ads, can be overwritten in each ad configuration file
ad_defaults:
  active: true
  type: OFFER # one of: OFFER, WANTED

  description_prefix: ""
  description_suffix: ""

  price_type: NEGOTIABLE # one of: FIXED, NEGOTIABLE, GIVE_AWAY, NOT_APPLICABLE
  shipping_type: SHIPPING # one of: PICKUP, SHIPPING, NOT_APPLICABLE
  shipping_costs: # e.g. 2.95
  sell_directly: false # requires shipping_options to take effect
  contact:
    name: ""
    street: ""
    zipcode:
    phone: "" # IMPORTANT: surround phone number with quotes to prevent removal of leading zeros
  republication_interval: 7 # every X days ads should be re-published

# additional name to category ID mappings, see default list at
# https://github.com/Second-Hand-Friends/kleinanzeigen-bot/blob/main/src/kleinanzeigen_bot/resources/categories.yaml
categories:
  Verschenken & Tauschen > Tauschen: 272/273
  Verschenken & Tauschen > Verleihen: 272/274
  Verschenken & Tauschen > Verschenken: 272/192

  delete_old_ads_by_title: true # only works if delete_old_ads is set to BEFORE_PUBLISH

# captcha-Handling (optional)
# To ensure that the bot does not require manual confirmation after a captcha, but instead automatically pauses for a defined period and then restarts, you can enable the captcha section:

captcha:
  auto_restart: true  # If true, the bot aborts when a Captcha appears and retries publishing later
                      # If false (default), the Captcha must be solved manually to continue
  restart_delay: 1h 30m  # Time to wait before retrying after a Captcha was encountered (default: 6h)

                  # the bot logs a warning and uses a default interval for this run:
                  #   - 1d for 'prerelease' channel
                  #   - 7d for 'latest' channel
                  # The config file is not changed automatically; please fix your config to avoid repeated warnings.

### <a name="ad-config"></a>2) Ad configuration

Each ad is described in a separate JSON or YAML file with prefix `ad_<filename>`. The prefix is configurable in config file.

Parameter values specified in the `ad_defaults` section of the `config.yaml` file don't need to be specified again in the ad configuration file.

The following parameters can be configured:

```yaml
# yaml-language-server: $schema=https://raw.githubusercontent.com/Second-Hand-Friends/kleinanzeigen-bot/refs/heads/main/schemas/ad.schema.json
active: # true or false (default: true)
type: # one of: OFFER, WANTED (default: OFFER)
title:
description: # can be multiline, see syntax here https://yaml-multiline.info/

description_prefix: # optional prefix to be added to the description overriding the default prefix
description_suffix: # optional suffix to be added to the description overriding the default suffix

# built-in category name as specified in https://github.com/Second-Hand-Friends/kleinanzeigen-bot/blob/main/src/kleinanzeigen_bot/resources/categories.yaml
# or custom category name as specified in config.yaml
# or category ID (e.g. 161/278)
category: # e.g. "Elektronik > Notebooks"

price: # without decimals, e.g. 75
price_type: # one of: FIXED, NEGOTIABLE, GIVE_AWAY (default: NEGOTIABLE)

special_attributes:
  # haus_mieten.zimmer_d: value # Zimmer

shipping_type: # one of: PICKUP, SHIPPING, NOT_APPLICABLE (default: SHIPPING)
shipping_costs: # e.g. 2.95

# specify shipping options / packages
# it is possible to select multiple packages, but only from one size (S, M, L)!
# possible package types for size S:
# - DHL_2
# - Hermes_Päckchen
# - Hermes_S
# possible package types for size M:
# - DHL_5
# - Hermes_M
# possible package types for size L:
# - DHL_10
# - DHL_20
# - DHL_31,5
# - Hermes_L
shipping_options: []
sell_directly: # true or false, requires shipping_options to take effect (default: false)

# list of wildcard patterns to select images
# if relative paths are specified, then they are relative to this ad configuration file
images:
 #- laptop_*.{jpg,png}

contact:
  name:
  street:
  zipcode:
  phone: "" # IMPORTANT: surround phone number with quotes to prevent removal of leading zeros

republication_interval: # every X days the ad should be re-published (default: 7)

# The following fields are automatically managed by the bot:
id: # the ID assigned by kleinanzeigen.de
created_on: # ISO timestamp when the ad was first published
updated_on: # ISO timestamp when the ad was last published
content_hash: # hash of the ad content, used to detect changes
```

### <a name="description-prefix-suffix"></a>3) Description Prefix and Suffix

You can add prefix and suffix text to your ad descriptions in two ways:

#### New Format (Recommended)

In your config.yaml file you can specify a `description_prefix` and `description_suffix` under the `ad_defaults` section.

```yaml
ad_defaults:
  description_prefix: "Prefix text"
  description_suffix: "Suffix text"
```

#### Legacy Format

In your ad configuration file you can specify a `description_prefix` and `description_suffix` under the `description` section.

```yaml
description:
  prefix: "Prefix text"
  suffix: "Suffix text"
```

#### Precedence

The new format has precedence over the legacy format. If you specify both the new and the legacy format in your config, the new format will be used. We recommend using the new format as it is more flexible and easier to manage.

### <a name="existing-browser"></a>4) Using an existing browser window

By default a new browser process will be launched. To reuse a manually launched browser window/process follow these steps:

1. Manually launch your browser from the command line with the `--remote-debugging-port=<NUMBER>` flag.
   You are free to choose an unused port number 1025 and 65535, e.g.:
   - `chrome --remote-debugging-port=9222`
   - `chromium --remote-debugging-port=9222`
   - `msedge --remote-debugging-port=9222`

   This runs the browser in debug mode which allows it to be remote controlled by the bot.

   **⚠️ IMPORTANT: Chrome 136+ Security Requirement**

   Starting with Chrome 136 (March 2025), Google has implemented security changes that require `--user-data-dir` to be specified when using `--remote-debugging-port`. This prevents attackers from accessing the default Chrome profile and stealing cookies/credentials.

   **You must now use:**
   ```bash
   chrome --remote-debugging-port=9222 --user-data-dir=/path/to/custom/directory
   ```

   **And in your config.yaml:**
   ```yaml
   browser:
     arguments:
       - --remote-debugging-port=9222
       - --user-data-dir=/path/to/custom/directory
     user_data_dir: "/path/to/custom/directory"
   ```

   **The bot will automatically detect Chrome 136+ and validate your configuration. If validation fails, you'll see clear error messages with specific instructions on how to fix your configuration.**

1. In your config.yaml specify the same flags as browser arguments, e.g.:
   ```yaml
   browser:
     arguments:
     - --remote-debugging-port=9222
     - --user-data-dir=/tmp/chrome-debug-profile  # Required for Chrome 136+
     user_data_dir: "/tmp/chrome-debug-profile"   # Must match the argument above
   ```

1. When now publishing ads the manually launched browser will be re-used.

> NOTE: If an existing browser is used all other settings configured under `browser` in your config.yaml file will ignored
  because they are only used to programmatically configure/launch a dedicated browser instance.

> **Security Note:** This change was implemented by Google to protect users from cookie theft attacks. The custom user data directory uses a different encryption key than the default profile, making it more secure for debugging purposes.

### <a name="browser-connection-issues"></a>Browser Connection Issues

If you encounter browser connection problems, the bot includes a diagnostic command to help identify issues:

**For binary users:**
```bash
kleinanzeigen-bot diagnose
```

**For source users:**
```bash
pdm run app diagnose
```

This command will check your browser setup and provide troubleshooting information. For detailed solutions to common browser connection issues, see the [Browser Connection Troubleshooting Guide](docs/BROWSER_TROUBLESHOOTING.md).
