Configure the message content and targeting:

| Parameter                          | Type    | Default | Description                                                                                                                                                                                                                       |
| ---------------------------------- | ------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **message**                        | string  | —       | Template for the message sent to sellers. Supports dynamic variables (see below)                                                                                                                                                  |
| **fetch\_since**                   | string  | null    | Stop scraping when items older than this threshold are reached (based on `last_publication_date`). Use a relative duration (24h, 7d, 2w) or an absolute date (YYYY-MM-DD HH:MM:SS)                                                |
| **fetch\_since\_timezone**         | string  | null    | Timezone for interpreting an absolute `fetch_since` date (e.g. `Europe/Paris`). Only applies when `fetch_since` is an absolute date — ignored for relative values like `24h` or `7d`. See [supported timezones](/docs/timezones). |
| **max\_results**                   | integer | null    | Maximum number of listings to process before stopping                                                                                                                                                                             |
| **max\_unique\_results\_per\_run** | integer | null    | Maximum unique results across all tasks in a single run                                                                                                                                                                           |

## Message Template Variables

The message parameter supports dynamic variables that are replaced with listing-specific values:

| Variable     | Description                                            |
| ------------ | ------------------------------------------------------ |
| **#title#**  | The listing title (e.g., "Appartement 3 pièces 88 m²") |
| **#pseudo#** | The seller's display name/pseudonym                    |

## Squid Settings

Configure general squid settings:

| Setting                     | Type    | Description                                             |
| --------------------------- | ------- | ------------------------------------------------------- |
| **name**                    | string  | Display name for your squid configuration               |
| **concurrency**             | integer | Number of parallel message sending threads (default: 1) |
| **export\_unique\_results** | boolean | Export only unique results (deduplicated)               |
| **to\_complete**            | boolean | Run until all tasks complete                            |
| **no\_line\_breaks**        | boolean | Remove line breaks from results                         |

<Tip>
  Example message template: "Hello #pseudo#,\n\nI am interested in your listing: #title#.\n\nPlease contact me via Leboncoin messaging.\n\nThank you!"
</Tip>

<Warning>
  Keep concurrency low (1-2) to avoid rate limiting from Leboncoin.
</Warning>

<Note>
  The same message will not be sent twice to the same listing (duplicate detection via message\_hash).
</Note>
