Scripts de Référence - Passe Marché

Vue d'ensemble

Cette section regroupe tous les scripts bash, exemples curl et utilitaires pratiques pour l'intégration avec l'API Passe Marché. Ces scripts sont des outils complémentaires à la documentation technique principale.

Configuration des environnements

Tous les scripts utilisent la variable BASE_URL. Définissez-la selon votre environnement :

# Staging (recommandé pour le développement)
export BASE_URL="https://staging.passemarche.data.gouv.fr"

# Production
export BASE_URL="https://passemarche.data.gouv.fr"

Consultez la documentation des environnements pour plus de détails.
